Here's the issue with your desire. It sounds great to you as someone who doesn't want to deal with annoying shit, but you can't make something weaker than fair to cut out the "annoyance".
Look at it the other way, What about champs that "feel" weak but are actually strong? Say, for example, old Sona. She was balanced, but didn't feel good to play AS because you didn't really do anything. Should she have been buffed to make her feel fun regardless of viability?
Or as a champ main of a champ in that category. Personally, as a top laner, I hate hate hate tryndamere. It's annoying. He annoys me. 5 seconds off pure freedom seems intensely strong to me, and difficult to deal with. he either smashes lane and free turret dives, or loses lane, but has all the tools to get the fuck out with his life anyway. But objectively I understand that he is balanced, and nerfing him would not only be unfair to his mains, but it could shift the meta. It would allow champs that Trynd keeps out of top lane to step in. He is the gatekeeper of splitpush, and if he gets nerfed, then someone who already does something else unique will also become the best splitpusher, possibly pulling them up into a powerful spot. Think of someone like Jax or literally any tank with zzrot. I admit, Trynd isn't the only thing keeping them down, and Jax beats trynd in a duel, but the point is that if trynd cannot be the king of split, then someone else will be, and if Malzahar can't be the king of "fuck this one guy in particular" then we might see other champs more commonly looking for a similar outcome,.
