Actually all of the heroes is easy to used. But it depend on you if you already have an experience playing something thay like dota2 , for example League of Legends. I do playing lol and before, im still not playing dota2, but when i tried it. its just the same, jusg the heroes,map,graphics and items is different. You can any hero, a special thing is, you been needing to memorize the skills of heroes. For me, Drow ranger because thats the first hero that i used tho when i tried to play dota2. Drow is compatible to all of the beginners , probably , one of the easy hero because she only have three actice skills but her one skill is just makes your attack high (Third skill). You can define a easy hero in the skills of it, those heroes with only 1-2 activate skills (Some easy heroes only have 1-3 activate skills) and the rest is passive. for example : Facelessvoid, drow ranger, juggernaut, ursa, troll warlord, ursa, bounty hunter, riki, sven, and etc. Just a few info, in the philippines , those players there were saying the other heroes "baby" or baby hero , probably cuz of their op skills.
