As of right now, his W lacks clarity. To define and address the problem: as of right now, casting Void Swarm feels unresponsive. A larger visual effect like a purple burst would make playing with and against it healthier. Also, the voidlings currently stand within each other's models, which, aside from not looking very good, also gives Malzahar a pretty high amount of hidden power. I propose making voidlings not physically interact with units so that they may stand next to instead of on top of each other, while not inhibiting movement of lane minions and champions.
