@Geckur0 Actually someone randomly running into a gas trap, at any range, is part of his best qualities. I can see which trap you've triggered, how far away your team is, and even prevent you from bunkering in a building I previously left for a few moments. OR hinder you on your way to ring by filling a tunnel and preventing your advance. These are actually caustic's strong points, what you are attempting to make out as pointless is incorrect and since you said it yourself "I don't play caustic" so asking for MORE nerfs isn't appropriate, because you literally are asking to break his legs without having actually experienced the problems when playing him.
With regards to people respecting or not respecting the gas, the problem is his lategame ranked play is great, just look at his pickrate during ALGS, but elsewhere his performance drops because of skill gap. There are two sides of the spectrum. The cautious enemy players respect the gas, allowing the traps to do the job of area denial. However the reckless and / or skilled player pushes through and ignores the gas. The problem is there is no punishment for this. There is very small consequences for someone bulling past the gas when they know you are at a disadvantage beyond it, taking 10 at best pips of damage. We can no longer put the traps in plain sight, so layering gas traps is even more difficult covering an area, ontop of being basically neutered if the ring should end in an open field, at which point I can't deny an area with anything other than my ultimate, which has a 3m cooldown. His kit is out of date compared to the other defensive legends, most of which have a long lasting ultimate that continues to work while caustic has only one chance to stop you from advancing should the gas traps fail or be useless because of the location.
As for the gas being indestructible I agree that was an issue, as invincible walls are bad.
I don't want to outright kill you with my tactical, I want to be able to defend with something other than my ultimate if you swoop in from behind catching my character unaware. I want to hold down a building properly without having to literally drown my teammates in my own gas doing so (because it hinders allies sight too). I want my damn tactical to be a colour other than lime * green so I can see the damn outline properly.
I want a balanced character database that doesn't take a plural of SEASONS to achieve.
