League of Legends is on of the enemy of dota2 ,
to be honest league of legends for me is for kids, sorry for those who are playing LoL , why ? because you can activate your skill by pressing Q,W,E,R and spells for D and F, in all hero and it so easy to memorize but in dota2 its a little bit different , i am not biased im just telling my opinion about it , but if you let me choose one ill rather play dota2 :) but it depends on you , what is the taste of you in terms of playing online games. ^_^
