Chamber change, not a groundbreaking nerf.
Also, obviously this won't happen. It's more effort than riot would put in for an agent change.
So:
Remove Chamber trip
New ability : Designer
cost 350 credits, one use.
It's a 50 armor heal.
Whoever it's used on has a special glow
Why?
In the lore, Chamber is a weapons manufacturer. He can make a fucking piece of armor. He's made a teleporter and multiple guns, he can make armor. Fits the lore of the charecter.
In game, it nerfs Chamber a lot. He is a whole different agent. No longer can you puck Chamber as a sun for KJ or Cypher. Chamber is now a flex like sage. He focuses on picks, while sage focuses on delay. He can't solo hold as well, he has nothing to play off alone, he can't hold as aggressive angles as efficiently because he doesn't have the safety. We also don't have an Armor based heal, so it's a new type of heal. My person built of this is that he cab only use it on himself or an ally who had bought armor that round. Then, the special glow is so the enemy knows its been used already. Not busted, but a good ability that forces chamber to either play more with the team or allows him to be more aggressive, pushing in wise.
