I think the changes will go as fellow:

Galakrond max Battlecry: 8/8 rush -> 6/6 no rush

Galakrond Hero Power: "Summon a 1/1 with rush.

Shudderwock: Added text: "This minions cost can't be lowered".

Quest (Corrupt the waters): 6 Battlecries -> 10 Battlecries.

Mogu Fleshshaper: 3/4 -> 3/3. (Increasing mana cost only BUFFS the combo with mutate/evolve, it's best to nerf this by changing the stats.)

Faceless Corruptor: 5 Mana 5/4 -> 6 Mana 4/3

Corrupt Elementalist:  + Overload 2.

Dragon's Pack: +2/+2 instead of +3/+3

:( Dragonqueen Alexstrasza:"Add 2 random dragons to your hand, they cost (1)".

Ancharrr: 3 mana 2/3 weapon -> 3 mana 2/2 weapon.

In the first days of a new expansion there isn't really a meta, everyone is experimenting with "bad/worse" decks to see what works and what doesn't. After like a week of a new expansion the meta is a bit more established and deck are generally a lot better than in the first week.

Do you change some (Tech)cards in your decks depending on which decks are more popular? For Example: When weapons are popular do you add weapon removal? or when mechnatized mechs are popular do you add silence cards into your decks? If not then that might perhabs be one of the reasons.

Every deck has its strengts and weaknesses. If your playing a deck that is being hard countered by another deck, and that other deck is the most popular deck in the meta, then it might be best to either pick another deck or class to play, preferably one that counters the most popular deck, so you can grind wins. 

Also i don't know how well choose druid is doing these days, it was a strong deck but it's been slowly declining. But secret highlander hunter is a strong deck. Maybe you were unlucky with your matchups/draw.

Altho switching classes might remove a lot of fun if your forced to switch from your favorite class to the one you hate to play most. Also changing your deck to counter the most popular one might mean you have to play archetypes you also dislike. (For example you might be a control player, but you have to force yourself to play aggro decks to win) It might be a good idea to ask your friends what deck they reached legend with, maybe they can share their decks with you

Sorry for this big comment, i hope it might help you at least a tiny bit!

I'm playing mostly Singleton/Highlander/Reno Quest Mage and it's a lot of fun! With good opening hand i'm often am halfway quest on like turn 2 or 3. Dune Sculptor is an Insane, and often game winning card! I'm also wondering why no one else is playing it, considering it counters Control Warrior pretty hard. (In my experience at least, currently 8-0 against control warriors) Perhabs people don't like this quest because they dislike RNG? Personally i really like RNG because it makes every game feel so much different, despite playing the same deck.

Actually this card can be put into Dragon Paladin, Because it can pull Twilight Drake.

Edit: It can also pull Faceless Rager

Favorites: Rogue, Mage & Warlock

I love playing Tesspionage Rogue (Too bad i nearly can't becuz too much aggro) it is super fun, and who doesn't like topdecking 1 mana pyroblasts/King Crushes. I really like Khadgar+ Jen Eli mage for the double Ragnaros, But i never use Conjurers calling because i find it too disgustingly good to play. I really like playing control Warlock (Mainy in wild)

I Like Shaman, Paladin & Warrior. I like playing Quest/Spell Paladin in Wild, Its pretty fun, and Stormbringer/evolution shaman is really fun too. Bomb warrior was fun in the beginning of ROS, but these days i'm having more fun with Big/Dimensional Ripper warrior. Although i often feel like Warrior has a few too many board clears, And if warrior is dependant off those board clears, then i feel like Warrior as a class is in a bad spot.

I Dislike: Priest, Druid & Hunter. Priests are just annoying and unfun to play against in general. And i "Love" playing wild and running into OTK Priest, Big Priest, or Quest + Million Bounce Effects Priest. Although having said that, Thief Priest is pretty fun. Druids are just i.m.o. the most annoying class. Infinite walls with Hadronox + Witching Hour, Token Druid, OTK Druids. Druids can pretty much do everything. And i dislike Hunter, because Facing a hunter, or playing as hunter is pretty boring.

Weird, i can still play on my Phone (Android System), it's working without problems. I can get into games and stuff no prob, BUT i am still on the old version of HS (Pre-Buffs). (And arena is disabled) I Looked on the Play Store but i don't see a update for HS... Perhabs blizzard removed the update from the play store, but those who already downloaded it are now stuck being unable to load/play the game? Seems like a BIG screw up on blizzards side.

That Prep Nerf is really significant. This won't just nerf Tempo Rogue, but ALL Rogue archetypes.

R.I.P turn 4 sprint, The tak Nozwisker into Prep espionage Combo now costs 9 mana. (Also i think the Prep->Myra's->Nomi is delayed now by 1 turn) R.I.P Turn 2/3 (Coin->) Prep-> Espionage + Augmented Elekk Combo, its turn 3/4 now. Wait, Prep + Vanish is now 4 Mana as well. Welp Rogue is gonna have A LOT of trouble against aggro decks like Token Druid, Beast & Mech Hunter & Murloc/Aggro Overload Shaman.

The Raiding Party/Miscreant Nerfs Are Fine i.m.o: It wont Affect Miscreant that much, And Raiding Party was WAY too good of a draw card for only 3 mana. (Conidering you can essentially "Control" which cards get pulled)

Elysiana nerf is completely fine. A card with such a powerfull effect should be hard to bounce. (Just look at Shudderwock)

To me, The new expansion is pretty Good. A good amount of decks are viable, and there are some fun decks like Battlecry Rogue, Ooze/muckmorpher Shaman & Portal Warlock. We also got the "revival" of the silence priest archetype in standard. AND new archetypes like ooze/muckmorpher shaman & Bomb warrior.

Big Warrior is also pretty fun, but i feel like warrior has so many board clears that warrior players can just "waste" board clears, generally without the other player being able to punish them for it.

As a (Burgle) Rogue player, i don't like that Rogue got so many Tempo/midrange cards to combo with the burgle rogue archetype, because it pushed the archetype from a more control-ish deck into a "mE SMOrc, FaCe iS tHe PlAcE" type of deck/archetype. Most likely because people pick waggle pick over Spectrall Cutlass (Despite it being the only rogue class card with lifesteal)

Despite all that, this expansion has been pretty good to me. Anyway, those were my thought on this expansion. Hyped for the solo content, from what i saw on the stream its WAY better then Rumbe Run, but we will see.
