If Malzahar gets reworked, I want him to have a new ult.
Point and click Suppression CC is not really a good idea. It makes him the worst thing to ever play against when strong but useless if the enemy can easily negate it.
Current ult and pre rework ult aren't good to have in the game.
I'd want to see him get a new ult and kit to show him being a prophet of the void or a type of "void mage".
He could still have a supression, hell it can be similar to his ult right now but not instant point click CC. I dont know how to change it or give him a new ult but Warwick's new ult is friggin awesome. He either leaps from miles away and tears you to shreds or he misses and awkwardly walks away.
