Nerf Maw of Malortius shield like you did Zhonyas.
Since Riot stated zhonyas was too safe, they nerfed the cooldown to 120 seconds from 90 seconds. And yet on the other side of the damage discipline, Maw is available every 90 seconds. So basically, Riot just makes an unfair advantage for mostly midlanes on the AD side. If you nerf the main 1v1 ability on the AP side, you should follow suit on the AD side. The favoritism is real.
. Now granted those are all items vs AP, and that is what this discussion is focused on. Im sick of seeing all AD teams.
and

) but only melee champs get mr per lvl and ranged champs dont they are stuck with flat 30 mr unless they build MR
