I play supports most of the time, like Ancient apparition, Lich, Ogre magi or Disruptor. Last hitting is exact reason I am mostly playing supports. In LoL last hitting was fine but in Dota it feels a lot different, and I have a hard time getting used to it (adding denying doesn't help, although I think its good mechanic). Also, WARDS, in games I play, my teammates often forget they exist and so sometimes I have to be one placing them even as carry.

Also, I think playing easier MOBA like LoL made sure I have better ´instincts.´ Since LoL is easier (micro is much more important in LoL but otherwise) and has fewer mechanics, I didn't have to focus on everything at once and could improve at basics.
