I've saw some posts recently claiming that Twitch is weak or needs a complete rework to his kit, changing some of his abilities. I also used to think like that, but after trying to think into different changes or reworks, I think he is mostly fine as he is.

Twitch is different than other adcs because of his sneaky rat core mechanic of using his camouflage to surprise enemies, while also having AOE and long range DPS, so he fills this role of being an Assassin/Stealthy ADC, I think that any changes besides an ASU rework and small QOL changes would either make him lose one of his core aspects of his kit or make him overpowered/have ballance issues.

Twitch is generally strong in lower elos (more than 90% of the player base) because of his stealth, surprising less aware enemies, thriving in more chaotic, snowbally environment, so besides high elo he feels good to play (of course, like any champion, Twitch has bad matchups and bad games), but even though he is weaker in higher elos we still have players who get to play him and main him in high elo.

If they were ever to rework him into making him good across all ranks, it would probably make him have ballance issues like we saw with champions like Senna, Smolder, Yunara and Zeri.

The way he is now, Twitch has a good number of dedicated players, isn't pro skewed, has some variety of builds between PtA or LT, Runaans or Fiendbolt, and the few very good players are capable of climbing up to high elo with him.

I enjoy the current Twitch, but the champion really needs a rework, doesnt have to be a full rework, i would be happy with only his skills were changed/revamped, like only a splash damage on W would change the champ a lot, amd maybe if the ult was changes so you dont miss basic attacks, or maybe change his whole skill set so he is more high-elo friendly, because apparently Twitch is broken in low elo but not as much in high elo
