Think of this... What if Blizzard made a game like this, and did a HotS like thing by compressing the "waiting around doing nothing" time. They brought MOBA play down to 15 to 30 minutes, instead of 1+ hours.
That's not my kind of game either. I'd prefer fast-paced matches. If I'm to wait around, I'd rather do so in sligle-player where I can pause or reload saves.
