Mage and Warlock should not look at it on the basis of the win rate, but rather on the basis of passive gameplay.
In general, you should reconsider your combo deck philosophy. Damage peaks of up to 96 damage from hand are just bad design, as are cards that simply say I’ve won (priest quest).
That is definitely better.
Combos have a raison d’être, but more of the board, so the opponent can do something about it.
But then only with damage peaks that require some preparatory work and do not directly pulverize the entire life bar.
OTK Hunter is a positive example.

Blizzard thinks they have understood the players, but leaves me with a lot of doubts about some of the statements that have already been made. Hearthstone needs to become more affordable. If you want to have all the cards, and that is what most players want, you can put 130 euros on the table. A fair price for an expansion?
Everyone I wanted to bring closer to the game has already turned down the price.

Then strength is invested in the umpteenth game mode, whereby the standard mode is completely neglected. Ok in this regard it has got better with balance patches and regular content, but a tournament mode with several game options (best of …) is still missing after 7 years. We still have to grind up the ladder, bored.
Let’s look at the competitor Magic, all of this already exists.
But according to Blizzard, the players don’t want that aha …
You make the same mistake as you did at WOW, that everything is made too easy. We know the result.

Sure, getting started should be easy, but to keep players you have to be ambitious if people are to deal with it in the long term.

Classic mode is quite nice for in between, but it quickly gets boring. 40 euros for 10 packs, even if they are golden, is a bad joke for a mode that should be more free. Blizzard has still not fully figured out its pricing policy and you cannot compare it with real card games, as there is little value here. Still way too expensive. This offer made me smile tiredly.
