The game will always be anti melee until supports as a class are nerfed significantly.
Support current powerlevel means that if you are playing a melee champ that isnt a tank you're useless after the 25 min mark, and it warps the whole meta.
It forces bruisers to splitpush, it forces melee ad champs to be unviable, it forces assassins to be unviable, it makes adc the only viable glass cannon class and makes tanks the only viable melee class, not only that but it also forces the game to be only around 5v5s with barely any other viable play styles.
Im going to be showered by downvotes due to the support favoritism around here but the game was better when supports werent as broken as they are now, and its not like supports were shit back then either but the whiny players wanted a broken ball of stats class and they got it now.
