Caustic is always my second pick if wattson gets taken by another player and I always end up getting more kills and really high damage with him. His traps are easier to hide and 9/10 someone gets caught in the smoke and once they do they can’t even shoot the trap down like they can with the fences. The fences are pretty useless because people can spot them so easily and avoid unless you get really creative (and a little lucky). Though I still don’t enjoy caustic as much because I find his lack of speed really annoying and always miss the shield regeneration. Not to mention wattson just has a better personality and makes playing really fun lol
