Dude, it's a Blizzard game. It'll do fine.
Let me use my magnificent powers of pattern recognition to tell you exactly how this will go:
The mighty minds of the internet will wear their pale, chubby fingers down to bleeding stubs as they bemoan each and every facet of the game as a travesty and a grievous affront to all True Gamers.
Then the game will come out and it will be bought and played by a metric fuckton of people. Many of the aforementioned mighty minds likely among them.
PS. And just to be clear, I'm not saying this out of some fanboyish impulse to defend Blizzard or their decisions. I was largely unimpressed by SC2:WoL, I didn't buy HotS or D3, and I don't play WoW, Hearthstone or that new MOBA of theirs.
