30cards isn't gonna shake the meta too much anyway. Probably spent too much time on the pve stuff, which will be fun I'm sure and I'm happy with that but they really need to get another expansion out before the end of the year with a bunch of cards and not all of them necessarily thematic, at least not mechanics wise, can be like Warlords of Draenor theme with orcs and shit, don't even know what's in there. And it needs 60+ cards.
They might have to decide fixing charge creatures at some point though, the core of most of their issues that resulted in many nerfs is that charge applies everytime the creature is resummoned(panda and shadowstep mostly). A creature should probably just only attack once a turn, regardless. So you can shadowstep Leeroy but you need to wait next turn to play it again(or you can play it but can't attack, which would be dumb but eh). They'll probably nerf shadowstep or something instead though, that's how they fixed warrior OTK too, nerfing charge(the card), worgens and whatever else I forgot.
