NERF caustic Traps

I can't say I've ever played Wraith - was a Caustic main for a while, now trying out different legends each time I play.  I just find the "hold and secure" play style doesn't match well with how much 3rd partying happens in the game today.  While I'm waiting for gas to dissipate, the team inside is healing up and I'm getting pushed by a 3rd squad.  Usually, the best thing to do is run away, let them fight each other and come back to finish things off.  Not as much fun as seeing things through - it's the action of the game that suffers.  I have no idea what the W key comment is - I'm assuming that has something to do with PC - I only plan console.  Look, I get that my point is frustrating for Caustic mains, and I feel for everyone that he got nerfed.  But really, it is a lot of fun to try new legends out and learn different play styles.  Hold and secure is not the only way to go.
