@CrazyPlays54 His gas cloud ultimate could cover a lot larger area and be taller, for one. In World's Edge he is beyond useless in the open, so if you play as him you have to stick to enclosed structures - which only works if your teammates also agree to this plan.
Caustic gas should cause more damage per tick, with the tradeoff being it lasts a shorter duration. As someone else here mentioned, I've set off his gas ultimate and had opponents saunter in, walk through the gas and even perform a finisher move, all without taking much damage. The little number damages floating by them like -9 doesn't really inspire fear.
The disorientation effect of the gas should be increased too.
One thing they could do that might make the traps cooler is once you have 5 of the Nox canisters up, say, they have an invisible electronic eye between them that sets them all off if the beam is broken. More like a laser trip mine. I've seen players walk really close to a canister and not set it off, so maybe the sensitivity can be increased too.
