Malzahar is so unfun to play against.
Listen, I don't care if you think whether or not Malzahar is overpowered, he's simply the most anti-fun champion to play against. Let me explain.
Malzahar will press E + W and clear the wave and permanently push you under turret for most the laning phase. Unless you're playing a waveclear monster like Xerath, there's simply no possible way to match wave clear with him. His E also gives him mana refund, so it's not like you can wait for him to go out of mana. Thus you're going to miss a ton of a farm and he's going to slowly and casually wither your turret to nothing.
It's also too hard to trade against him because of his shield passive. It gives him 90% damage reduction and it can linger around for multiple spells. It also gives him CC immunity so good luck trying to gank him.
Honestly the worst part is his point-and-click nuke suppression that CANNOT be cleansed except by a QSS (a component that only builds into an AD item). This ability just removes me from the game. If the counterplay is "don't get into range of him", then how the hell am I supposed play champions like Ekko into him? Getting into melee range is about the only way I can do damage, so basically what you're saying is "never do damage", or I have to wait until he already uses it on someone else before I can even enter a fight, which might already be too late.
Right now Malzahar has a 53% winrate and 5% playrate according to op.gg. But that's not what bothers me. What bothers me is that he makes me completely useless, both in laning phase and in teamfights. He is the highest form of anti-fun in this game that I can think of. Please give his kit some counterplay, I don't even mind if you buff him in the process.
That's all.
cough and build
as it ruins a lot of his damage potential
