Malzahar does too much damage, but voidlings have too little health
Malzahar currently:
1400 dmg at lv16 with e + r alone against a 1600 hp target. Then add in w, q, deathfire touch and
... If you e + w + r any carry at almost any point in the game, if you get full duration of your r, they are 100-0'd
rank 5 voidlings are ONE SHOT by a lv11
w, and literally every other ability in the game
From what I can tell playing him, and also by his win rate spike, his ap ratios are just too high. But seriously the voidlings are still so problematic. They either mow someone down during your r when they can't one shot them, or they aren't in your r and they just one shot them
