I'm trying so hard to like his new kit. I like the idea they were going for--after all, now the dream of 'an army of Void-poros' can finally become reality. It's cute and amusing walking around with 5, 6, 7 little Void-porolings scampering along behind you.
However, once the thrill wears off, you're left with a champion that will be unbalanceable. If anything, his combo is even worse than it was before--assuming they don't have QSS. By the time the suppression comes off, your horde of voidlings will have done the 'burst' for you. He's great at 1v1ing melee laners in top lane. However, I miss his old W. People have said that it 'had no place', or that you 'never used it outside of his ult' which is... complete and utter bullshit. I always thought he transitioned beautifully from a spectacular duelist to a late-game siege mage, laying down qs and ws to weaken the enemy team on their tower with his range.
I always thought Malzahar was sort of like a Venus flytrap. Relatively harmless (without his flash combo) until you get too close, or make a mistake. He was easy to punish, and punished people hard.
I played one matchmade game where I wanted to play him, but the other team got him first. Not wanting to lane against my main, I switched with somebody to take support, and let them have mid. My poor Brand got dumpstered by him (muahahaha) but that was the sad thing... even though the Malz won lane, he couldn't do anything else with it in teamfights. He can't keep any voidlings up, and since his E and R are single-target, he now only has his q to contribute to AOE teamfights, and his ult as pithy ADC crowd control.
Before there was all this payoff for landing the combo correctly. If you suppressed someone off your naughty pool, or didn't silence them, or didn't get aids off, you would not kill your target. Now you just brute-force your way to winning and constantly look for someone stupid to catch so you can actually get a voidling or two outside of lane or the jungle.
AP, lane Malzahar... the one you play against Yasuo and Zed... is dead. Once he's been nerf-hammered into oblivion, he will be stuck in the jungle and top lane, where he can actually have a chance of reaching his target. Ahri, Lux, Xerath, Ziggs... basically any champion with more than one form of CC in their kit and any amount of range will shit on him, and any mid-mage now has more damage and utility than he does. This whole thing was to have obvious reasons to pick a champion. Why the hell would you pick Malzahar now? I mean, once he's been nerfed and it isn't a free win anymore... why pick him? Because he has pets? Because of his passive? A passive you can buy in the store?
Before I picked him if the enemy mid was a mobile assassin, because the waveclear and burst suppress could ensure that you could deal with them and keep them from roaming bot lane and fucking your adc. Before I picked him into tanky teams because his aoe %hp damage was superb. Before I picked him into early-game teams because I knew I would outscale them (Ryalai's for utility... but now AP malz sucks ass...) with damage and utility.
Now what does he do? What does he do WELL? Once the Voidling problem is nerfed... there will be no damn reason to pick him.
