Hearthpwn

The buckets are randomly offerred but most are not randomly generated. They are hand-picked by the devs. That is why some (like dragons) have the same cards every time.

By the same logic, some classes just don’t have buckets for certain archetypes. Maybe Reno has no mech bucket. (But I’ve never tried Mech Reno, so it’s just an expample.)

There are some cards that really mess up your bucket and treasure pool. It can be different spell schools in your starting deck, including even 1 battlecry/deathrattle minion, or the new 2 mana amalgam.

I suggest you search up “hs duels decks” and click on some links and see what treasures and buckets people get offerred depending on their starting deck. Some treasures can be targeted with +80% success rate, like when playing Frost Shaman or Mycelium Druid. Analyze their starting decks and bucket choices and you might gain some insights on the drafting algos, which will help you when making your own decks.

Bro, the goal of any company is to maximise profits, we don’t live in an idealistic dream world where everyone can have everything they want for free. If you can pay $60 for a game on steam and play it for 30 hours, you can spend the same amount on HS if it fancies you. However, strongly agree that the game is way too expensive - if prices were 20-30% lower, maybe more players would start buying stuff.
As for the tabern pass, it’s one of the better deals and your desire to remove part of the rewards just because you want them for free would hurt paying players. Even if the Pass didn’t exist, you could still pay for packs to get the cards, it would just cost more. 

The paywall is the reality for everything now, and I don’t see a problem with it. You play a game you like, you pay to support it and get more stuff to play. It’s not like golden legendaries have +1/+1 like many similar mobile games do. Nevertheless, HS is still very expensive and I’d like to see a price cut. I’m no company manager, though.
