Might be a bad take but I think they give him back 2 teleport anchors and give a global trip back. BUT add 2 seconds on his TP and increase the range on between both anchors. I think this way he can have more of a global presence, but he doesn't have a get out of jail free card but a strong repositioning tool (similar to a yoru gatecrash). This way he can't just OP you and get away super fast and he has to be wary about his positioning and can't play insane off angles but can still get a pick and run away.
Don't flame me if you think it's bad, I think this change makes chamber more of a sentinel rather than a defensive jett.
