Riot you need to focus more on nerfing the powerful, not buffing the weak to match them
The steady flow of buffs to those that don't need them compared to the lack of nerfs on those that do is abysmally off.
Stop buffing those that aren't performing up to par with the top of the roster, nerf the ones dominating so we don't get another busted one to add to the list.
Nerfing Champions and items inherently buffs those they normally outperform.
We don't need another ADC abusing the ridiculous damage of

We don't need another tank dealing massive damage while building 0 offense.
We don't need more Assassins chunking targets with only half their abilities landed plus an Auto because of 
We don't need more Mages building cookie cutter
and rolling their faces on their keyboards in the HOPE of nuking an enemy before they get popped.
Fighters are a joke plain and simple, they get outclassed by so many others in the tank class due to the majority of them lacking high damage while building tanky, BUT THAT DOESN'T MEAN YOU NEED TO BUFF THEM TO MATCH, just nerf the overlords keeping them so miserably low.
And Supports are just... I don't know they're just there, they don't really do anything besides build bonus defensive stats for their carries, that or they become a second Mage in the hopes of whittling a target down enough for their Carry to effortlessly pop them.
Please look into tuning down the characters and items at the top of the roster, not breaking those at the bottom so they match, that'll just escalate the problems present in the game.
