Well whatever it is, I hope they understand these important details:
Most Malzahar main's like having voidlings, they just don't like the current mechanic. The old Hitpoint voidlings with frenzy were much better.
We would like to have the Void Pool back with our W. Maybe this can be achieved by combing the pool with 1 voidling spawn... or a 2 click method, 1st click = voidling, second click (withiin the right time) brings the Pool.
The main reason for having hitpoint voidlings is so that he is viable in the jungle again, and it also helps that he can jungle the dragon. I don't understand why its OK for a Mordekaiser to be allowed to Solo Drag... and destroy turrets, even solo baron after getting the drag, but Malzahar should not be able to as a jungle? Makes no sense.
So, a good number of us Malzahar Mains, want to be able to Jungle.
Another issue Malzahar faces is that his ULT is so easily ruined. Practically EVERY Champ has CC now, and add to that QSS and Edge of Night, and the fact that Riot is giving new champs spell block as part of their kit really hurts Malzahar. Malzahar does not need a guaranteed ult, but perhaps only the CC part of it should be ruined... the damage should still take effect... LIKE IT USED TO BE.
Now, when someone CC's Malz or uses QSS the whole ultimate is destroyed. Yea, QSS even negates most of the damage from the ult.
That is new bug mechanic, and needs to be fixed.
His lack of mobility and the fact that he has no CC in QWE makes him overly vulnerable. His Shield USED to be good enough to help him there.
But they nerfed it, then nerfed it again, and again...
So, please return more of shield CC protection, and give him back his mobility.
Lastly, almost every other champ in midlane outscales him. So, it would be nice if his late game was improved. Perhaps give him additional bonus penetration for each kill he gets. That would allow him to scale at least.
