@OpponentKnot644 Not sure what you mean by "destroyed like doors"...unless you mean destroyed after the damage of two melee inputs after the Trap is activated.
If that's the case, then they would surely have to compensate and increase the gas damage. He's meant to lock down areas, so rushing that defense will have a bad penalty regardless.
IMO the only change to his Traps needs to be a recolor for friendly vs enemy. Too many teammates shoot down my cans when another Caustic is in the mix. Or maybe a trade off would be no recolor, but when a Trap is shot by a teammate it doesn't disappear 🤷♀️
