lets start by saying that its useless to nerf his sheriff or traps like they did with jett smokes, chamber and jett are broken for their possibility to play off angle, do the first shot and run away.
For me the best nerf for chamber is using his tp like the dismiss of reyna or jett dash, u can use it only after activating it with a countdown or only if you kill someone. He will always be broken even with 0 traps and 3 sheriff bullets coz playing off angle and manage to run away even if u miss its the most broken util ever
