Blizzard has always been slow in releasing games. Honestly, who cares if they release some mobile thingy in the meantine. I simply wont play it. There, drama fixed.
Well, but that's not the point, is it.
The point is - Blizzard created a cash-grab of a game, trying to hop on the MOBA trend that died in the meantime and when it was a financial failure, they are abandoning it in a pursuit of even sillier project. They WON'T make another good game.
It's not a drama. Actually it's pretty fun to watch as someone whose last Blizzard game was Diablo 2.
