Caustic gas seethrough bug
As you can tell from this link here:
Caustics gas is supposed to be a place where you can not see, move, or navigate through well. That is his domain as a deffensive legend, and the fact that the gas is so easy to see through and that the blinding effect is almost nothing can finally be adressed as a problem now that he has had the absurd damage reduced. (he never nedded a damage buff past starting at 4 per tick) He was never supposed to have his entire team work well in his gas in the first place and the fact that they nerfed him in so many ways in exchange for his team to be able to play in it is absurd. Change him back to what he was before you removed team slow from his gas and he will be perfect again. (I did enjoy removing team blindness but It would still be better than this) This includes the damage, trap shootout before fully deployed, damage with gas, ect. He was not meta then, but he was strong in a special way.
