Ranged vs melee
Ranged champions, both adc and mages need to take a hit in the damage department. They aren't on the front lines. They are safe. Have way too much poke as is. They have stuns and slows. They are now in every lane. Graves is the best jungler now, which is beyond stupid. Adc's and mages have taken over top. Mid has been infected for ages by champions not meant for the role.
It is bad enough melee champions have to go in and make it to the champions to fight, but to be out damaged in the end is really annoying. By the time they get passed the cc and the distance, they are cut down way too easily. No matter how many tank items or builds they have. The only solution is to cut the damage ranged champions have.
