you guys definitely should... believe me i was so against switching over to dota 2. i constantly bitched and nagged to my friends on how shitty and slow the game was but if you just force yourself to play, eventually you get used to it and the delay is barely noticeable.
one thing which made dota 2 bearable was just randoming every game. every game is different and you get to learn all the heroes. Plus the extra 200 gold is a great bonus
the next big thing that pisses me off aside from slow / delay in dota 2 is how the map is laid out. hon added an extra passageway @ bottom river, makes running around / ganking a lot more easier than dota 2
