I don't quite understand why people are so excited for Heros of the Storm... It just looks like Dota2 but with bnet2... Which compared to the Dota2 interface is horrible and is yet to even match the feature set of the original battle.net...
I am excited for it simply because it's a blizzard title with heroes I know the lore to. Let's not forget quality, and this isn't just being a fanboy - blizzard does put a lot of quality into their games. Not just in a graphical sense, but in a usability,
learning curve, tactical and UI perspective. They just do games right. I can especially say this about WoW. I have played just about every MMO out there. And I always end up back at WoW just because of the quality of the game.
My chips are on Heroes of the Storm based on those aspects alone. (And keep in mind, I am an old school dota player)
