Interesting how you assume the fighting in dota will ever stop and that civilization will somehow continue. What happens outside of the arena where they are defending the ancients 2 ?
My only experience with moba is totalbiscuit single draft disaster and awesomenauts.
After 3k hours the game is fun platforming turret pushing (espionage?) action.
The only arcana I'd almost bought was Legion Commander's one. By far the most stylish IMO. Phantom Assassin's has some cool effects, but a pretty ugly model. I'd rather a normal cosmetic with the arcana effects. Same thing with Jugg. Nice effects, fugly model.
