Rito should've nerfed W AoE and not W damage
If Malzahar was meant for single target lockdown, why can't he lock down tanks as well anymore?
Honestly, they should've gone the route they did with Soraka and Rammus and nerf stuff that wasn't contributing to his main strength, the AoE of W.
Though I'm probably biased because it was the main source of my damage with Malzahar jungle clearing, and I play Malzahar jungle.
