Druid is definitely something they've got a close eye on, but combo is much easier to play around, and druid has a lot of known weaknesses (mostly in board control). Anti charge tech is probably to come, but still. It's also much less damage. 

Never assume you understand how to do serverside work
Also it's not the entire company working on hearthstone, it's about 20 people

Vol'jin: Techy option for Control and Dragon Priest
Varian: Techy option for control warrior, hardly necessary
Nexus Champion Saraad: midgame option for priest, paladin, warrior, and mage
Confessor Paletress: Solid lategame in control priest. 

Those are the main cards to consider, none are a priority so you can mainly just relax and not craft anything for now. 

I would argue one of the main pains overall is getting pleasure from victory and pain from loss. Your goal is to improve, to play better, and to enjoy the games to there. Especially in a game with somewhat random outcomes, the short term games need to not matter to you at all, and all that should matter are the decisions. That tends to make the experience much easier to enjoy, and much richer. 

I'm sorry, neither Spelleater nor charged hammer are rng dependent. One is match up dependent, but both are very functional, if not particularly strong.
Hunter isn't necessarily bound to aggro. We see with midrange hunters of all sorts that the hero power can be used as consistent damage to compliment board control, rather than as a win conditon. Similarly, it can let you fill your deck with no damage as your hero power alone is a win condition in slow match ups, and its also a good set up for combo hunters. Rogue will always have weapon synergy, but in the past we've seen every kind of rogue from tempo to face to control to various different combo archetypes that have almost nothing to do with weapons. 
And in the past, the shaman totems were considered the strongest hero power in the game, with paladin considered screwed because the 1-1s were as good as shaman's worst totems. 
It's all a matter of gamestate and strength of individual class cards and archetypes, really. 
Instant into your hand cards are definitely a mechanic worth considering, but they also hurt the difficulty of creating appropriate curves by a lot. 

Play more games. Play games better. Write down what potentially could be different in your decisions, or just make mental notes. Control your frustrations, as they do little but blind. All there is to it. 

Manipulating, responding to, and working with randomness is in and of itself its own skill. 
An esport is a solid multiplayer game with consistent player vs player interactions that are compelling to watch and can be improved in and adjusted within. Hearthstone has that in spades.
The video above, as well as many others created by Extra Credits, show that that's what's important in an esports title. 
The winner of big events isn't relevant to the players, but to the fans, so randomness affecting outcome isn't really important there. 
What is important to players is who gets in and how well they do overall. Top 16 tends to be their priority, and getting there is usually a matter of skill, both within and outside the game. The game is thoroughly practicable, and there are lots of ways for players to improve.
Hearthstone also has an immense discipline requirement. Playing 20-50 games a day while never feeling emotionally affected by wins or losses, randomness going either way, or outcomes of tournaments is an important part of the game that lots of people are building towards, and that part is especially difficult in Hearthstone, and shows a line between good and bad players, as well as long term and short term players. 
Hearthstone elegantly fits the bill on all fronts. 

This trend of positive posts lately gives me strength

The general rule one must consider with the summoning effects is that if the effect could in theory effect the summoned card, it happens after summoning. Warsong commander by definition cannot give minions charge before they're summoned. So fixing that to work properly would actually be a complete destruction of the card and its text. Whenever was probably an attempt to simplify the card text as 'after' would have been stranger. "Does the card need to be on the board for the effect to trigger in a sensible way?" If yes, after, if not, before.  Knives and blasts could in some ways trigger things that kill the minion that got played, so yes. Those happen after. 
Illidan is actually a really unique card in that respect, as the fact that he interacts with both spells and minions means he has to go before summons, which leads to some crazy knife juggler explosive sheep sylvanas shenanigans where you can give your opponent deathwing to discard their hand, instakill them through playing jaraxxus, or trigger a mind control in a way that puts it in your hand instead of on the board. 

Keywords I think they're approaching properly. The magic resist effect is recurring, but it isn't as frequent and specifically interactive as taunt, windfury, divine shield, etc etc. Maybe in a set or two, it will be.

Fuck yeah hearthstone <3

Adding cards buffs other cards in a much more significant way than adding cards nerfs them. Patron buffed warsong commanders into absurd range. Motivations for cheap cycles buffs novice inventor, as do stuff like hobgoblin. Mysterious challenger buffs every paladin secret into usefulness, save eye for an eye which is still useful as a lesson in card value. The list goes on.

The long and short of it is this; team 5 wasn't prepared for the long term affects of their cards when they created the game. They didn't intend to invest into it this heavily back when they created cards like starving buzzard and warsong commander, and they had much worse designers back then. Those cards limit design space /ridiculously/. Nerfing them into the ground is a better approach than trying to find their sweet spot, as that lets them add 3 or less attack minions, or beasts, without worrying about breaking the game. The results have been excellent, and will continue to be.

sure theres grim war, secret pally, but Naxx provided for 'everyone'

Grim warr, secret pally, dragon priest, Dragon warr, totem shaman, demonlock and tempo mage, along with improving almost every existing deck. The only class left out was rogue, which is completely okay with me.

Lets simplify it, you have to get the Naxx cards and can create strong decks and do without any TGT/GVG/BRM cards.

Furthermore, I have dust sitting in the bank enough for most new legionaries, but I lack incentive to craft any of them, doesn't this show how poorly its done?

Your ability to judge what card is or isn't worth crafting doesn't make a set a failure. An expansion shouldn't demand that you get every card; that's barely reasonable for commited pros let alone casual players. You need a small flow of good cards complemented by interesting or fun cards. We had that this expansion! We had good cards in justicar and chillmaw, and decent legendaries in varian, gormokk, rhonin, Confessor paletress, etc etc. 

Before that, we had solid additions and compliments in general. Quick shot and imp gang boss improved decks without making them absurd, thaurissan snapped the game in half rather pleasantly, the list goes on. Any class can functionally do dragons now, all secret classes can do secret things, all weapon classes can do weapon things, the expansions have rounded out a lot of HS and this expac rounded out the most. I expect the next content release to push the game towards a new direction, whatever that is.

Fatigue warrior will never be comfortable against any sort of paladin. The point of fatigue warrior is to maximize the effectiveness of your hero power while going 1 for 1 or better with your 30 cards, usually a lot better with weapons and clears. Paladin's hero power is better than yours, especially since you're not applying the pressure of a control warrior. 

To combat secret paladin, slams/bashes, bghs, revenges, brawls, desperate mulligans, lots of options exist and lots of people are playing cw because of its relative comfort against most decks. Nowhere as bad as freeze vs cw. 

Looooooooooooooooooooore
