Malzahar's voidlings should have an indicator when they target you, like Yorick Minions
Just played a game where I was an aggressive Diver in a teamfight, and there was an enemy Malzahar. Malz had E'd me and dropped all of his voidlings on me, but I didn't know that they were even there until I got killed by them and looked at the death recap and saw that they did half my health. They are really hard to see in a teamfight situation when I'm focused on enemy champions and dodging skillshots, and this clarity change would be really helpful.
Basically when Malzahar E's you, and his minions begin targeting you, they should have a purple exclamation mark over their heads, like Yorick, to indicate that the minions there and are targeting you. Allies don't have to see this, it would busy up their screen with information they most likely don't need to know.
