Leveling idea

I personaly get really bored when i level characters and it would be a lot easier for me if there was a skip all quests button so if u done all the quests once in the league than u can press it and u can level by simply killing monsters instead of having to kill specific monsters to progress there could be lvl checkpoints(when u reach lvl 5 u get a passive skill point from a quest u would normally have done on that lvl)
