This is a new wave of bans that has not affected those players suspended by the first wave. As we mentioned in both our Recent Actions Against Botting in Hearthstone and Continued Actions Against Botting in Hearthstone posts, those found to be botting after the first wave will receive a permanent ban from the game.
Leeroy did actually appear in the world championships, in a Miracle deck by Tarei, and I have seen it still around. It's certainly not as endemic as it used to be, but that was the goal in the first place. Flare
We felt people were a little bit getting randomly screwed by Hunter if you had a secrets deck because it was no cost to the Hunter to remove them. Now at least you know that Hunter players need to make a sacrifice with Flare, in that they need to make their deck worse against non-secret decks if they want to keep that advantage over secret decks.
Auctioneer, mixed with the new Spare Parts cards from Goblins vs Gnomes, we thought that was pretty dangerous, and a change we had to make.
We did add some cards to Goblins vs Gnomes that are specifically good against Deathrattle decks. But The Undertaker is one of those cards that feels really powerful when he's hurting you, but if you draw him late in the game he's pretty terrible. We were paying attention to how people were using him, and looked at how we were playing against him, but we didn't feel he's nerf-worthy. He is very powerful, but it wasn't past the line for us.
We felt [it] was a little bit too efficient.
Buzzard is a little bit more unseen now though, but its mechanic, where you could draw your entire deck fairly consistently early on, we felt we had to change that.
The "Having too many cards" problem
There are a lot of games in this genre that solve this problem already. Also we have some ideas that are unique to Hearthstone that we think could potentially resolve these types of problems. One thing we're aware of is new players could find the game harder to get into, and harder to learn, the more cards we add.
We have ideas to solve those problems, but I think we're a little bit far off from those problems today.
