A series of beta invites went out today although I think an NDA is required, not sure.
The game is borrowing a lot from WAR but beyond graphics and sound, I think the game isn't borrowing much else. For the most part, it apparently is a DOTA style game with 5 'instant cast' spells on timers. I don't think macros are even going to be available, let alone addons. Of course I could be wrong.
For the most part, it seems like it's going down a completely separate route then WAR.
