usually people who dislike hon its cause their bad at it. HoN is not a game for noob , but since you mentioned you have play dota and LoL you should be able to play some no-stat or noob game. Many hero and item are direct port from dota so if u were decent at dota it should take ya like 20 game or so to figure the shit out then it start getting fun.
But i like i said dont be afraid if some1 start flaming you cause you are feeding =D
