NERF caustic Traps

Yup.  I hear you on that.  The problem I have is when Caustic uses a trap to block a door, and his team is inside healing up hiding behind his trap after he is down.You can't shoot down the traps through the door.  So you have to send a grenade at the door and wait for the traps to finish spewing gas and face his the rest of the team fully healed.  Kind of an OP move from my POV.
