I don't care for it. Built-in Delay really detracts from the game. It's not nearly as fast paced as HoN. HoN has recently been pissing me off though lately since I can't seem to get a good team for the life of me. Me and 2 of my friends always get 2 other people who have no clue how to compose a team/can't play any roles.
DotA 2 is still in beta anyways, so who knows what they'll do. But as it is right now? I don't care for it.
