I dont feel jett wil ever stop being picked until they nerf the dash. I suggest making it so you cant dash somewhere youre not looking.
So you want jett to be like yoru and not get picked? Sure she seems overpowered but she demands high mechanical skill from players and if played very well can produce god-like clips. And I would argue that raze > jett in some maps like split, bind and maybe even fracture. You'll notice that in champions, not every map has a jett. Just look at fnatic vs c9, neither teams used jett in split and fracture. https://www.vlr.gg/51283/fnatic-vs-cloud9-blue-valorant-champions-opening-d/?game=57953&tab=overview. Overall Jett's fun but isnt has overpowered as u think she is.
I feel like you have to be careful when nerfing Jett. Yes, she is the best agent and has been for about a year now, but she is also the face of the game. She's incredibly fun to play and entertaining to watch while representing what Valorant is. So, while I'm all for nerfing her, I'd rather not have Riot nerf her into the ground.
