Let's talk about Malzahar
First of all, I love Malz. When Zed, Yasuo, Kha, Kat, and Akali are running amok in Mid who are you going to lock in? Malzahar. When Nasus, Malphite, Darius, Renekton, and Mundo are harassing your carry who's going to stop them in their tracks? Malzahar. The absolute best thing about Malzahar is the feeling impending doom he brings to any champions he faces, no matter if they're assassins or tanks.
Back in golden age of WoW my main was an Affliction Warlock. Malzahar is the only champion in this game that gives me that same sort of playstyle: death by attrition. When Malzahar tosses his E on you, for the next four seconds all you can do is watch it widdle away at your health bar unless you do something quick to shield or heal yourself. If Malzahar throws his W down and ults you, you have to sit there helplessly and watch your health melt away unless your teammates come to rescue you. This is Malzahar in a nut shell - he is the prophet of your death. If there's only one thing I could ask Riot it's to keep this overall core identity in mind while looking into Malz. However I do understand that helplessly watching yourself die with no options to stop it...might be frustrating and not the easiest gameplay style to balance.
Malz - More game health issues than anything else. Counterplay's not great in particular, with Malz needing to just click on you and kill you given his squishiness, immobility, lack of reach, vulnerability to item system counters. Has a lot of distinctive stuff going on though.
Keep in mind that Malzahar's counter is his predictability. It's a mind game; it's a chess match. You know what's coming so you know what steps to take to prevent/avoid it. If you want to create more chances for counterplay (outside of items) I would focus on this aspect. Make his E more predictable on where it'll bounce. You could create a sort of "mark" in his kit, like Nidalee, that will then allow Malzahar to suppress them. That way it keeps the whole impending doom aspect of Malzahar in tact and makes his opponent think "Okay, I let him mark me and stuck around for him to ult me. I f'ed up."
Overall I would say his Q could be pretty different and the way his voidlings work could change, but what really makes up the core of his gameplay is his E, W, and R and the interaction of how his opponent can try to avoid them. If you can't avoid them, well...

or get rekt is not a healthy play style and he is zero fun to play against. pre 6 he is overall fine and has counter play. his Q hit box is wonky and need some work on clarifying when you will get hit and when you won't, his W is honestly just boring for everyone involved it does hardly any dmg unless you stand in it for full duration do you guys actually like this ability? if so why? i think a much better ability could replace it personally. his E is literal cancer, chemo and all its not a huge problem, but i don't see how a instant targeted dmg over time nuke is really fun for anyone, you can't dodge it and it takes no skill to use. not saying all skills need to be skill shots but some more counterplay/interaction would be better right? then we get to his ult, the pinnacle of anti fun in the game. malzahar click R on you then you just cross your arms and wait for the gray screen. QSS works wonders obviously(like almost too much) but you literally have no options outside of it. if you are an AP champ then you sacrifice an item slot for an other wise useful item to you. if your an AD champ like zed or talon vs malzahar then it builds into a really good item for you and you will pretty much always destroy malzhar and there isn't really anything he can do about since all his power is put into an ability that is pretty much useless against you now. i don't see how this is fun for anyone. have you guys ever played much against malz? cause it seems like you are only thinking from the perspective of the malz player. i don't have any friend thats really play malz that much so i really just don't understand. i just know that when i play a game vs
and
that i wish i could just DC and play a different game becuase there is no way i'm going to have fun playing against them.
or
into swain you have a many more options when playing the lane. lets do a comparison.
is a very hard match-up that is unwinnable for diana 1v1 laneing unless the swain player is a literal trashcan in a chair. the options diana has for this lane are
and get blue buff so that you can nonstop poke him until he eventually gets low enough to kill in one combo or force him to back/burn all his mana healing and miss cs
