Make Malzahar Q Function like Irelia E
It doesn't make any sense that Malz Q is so stationary while so many champions with dashes exist. It's hard enough to be an immobile mage player with every new champ having some kind of movement built into their kit. We should be able to press it twice and make it work like Irelia E. That's all.
You could also make it more thematically correct (it "opens portals" but some random purple stuff comes out) by having voidlings come out if the ability is not recast.

W, But have at a fixed angle, where you can change directions from left to right, or right to left, so You can use one side of the ability to quickly silence.
