Just because the op champs at the moment happen to be ranged
Doesnt mean theres a problem with how ranged and melee champions interact with eachother.
What is happening right now is that champions like Jayce/Kennen and Syndra are way too overpowered and those are completely anti melee (+ a few other popular picks) who dominate most champs in laning phase + outscales them, once those OPs get nerfed down everything will sort itself back.
Use ur brain instead of parroting eachother.
