Dumb idea: Malz should corrupt the rift

Ok, so someone told me that Malz should be a control/lockdown mage that punishes people for not being careful in his zone. Personally I don't fully see that beyond his void puppies.

But (like the madman that I am) this gave me an idea.

So brace yourselves, cause I'm about to talk about gameplay fantasy and HoTS (they aren't related).

In HoTS they have a character called Zegara who has a passive and one ultimate that actually terraforms the area around her and gives her offensive buffs. Being a Zerg character this fits pretty well.

And honestly she does Malz's fantasy better.

What is Malz? He's the damn profit of the void. He's probably one of the main summoners! But all he can summon are these little void puppies. And of course make you see the void, which I'll admit is very prophet like.

Personally I think Malzahar should actively/passively taint the land he walks hovers over. Make it more homey for the upcoming void beings. His little lane corruption could give passive buffs to his voidlings or even his own abilities.

I'm not fully sure how I'd implement this idea, but it does involve removing the spell shield and putting his visions on his passive (to better emphasize he's a DoT mage, his damaging spells (but not units) would apply his visions. Obviously there would be a cooldown between targets, but they would still spread the same).

Thoughts?
