Caustic :
Bad sides
Big hit box, slow, is countered by other caustic, his passive ability is just protecting himself from his own ability, his gaz affects his allies, the traps takes a long time to activate and are not very sneaky, has no protection nor survival ability, he has absolutely no mobility, his ultimate isn't really impactful and like any smocks, you can just see through if you have an aim that highlight your enemies.
good sides
He can counter other caustic, the gaz is a powerful tool if correctly used (damage, slow, blurred vision, enemies highligted, blocking line of sight, the trap itself can be used as a cover, let you know when enemies are nearby), low cooldown on ultimate.
My point of view here is, we shouldn't up the gaz. Because when you look at it, it is already powerful. It is not League of legends, we are not supposed to kill with our ability, or at least with certain ultimates. His does not fulfill this role and therefore has a little cooldown. Fair enough. We just has to use his ability at the right time.
What is bothering me though is one main thing : I get it that this game is first and foremost a FPS battle royale, and thus the abilities should vener get in the way of the personal skill with any given gun. BUT, based on the same logic, this character has some majors flaws in that regard. These are his low mobility and his gigantic hit box.
Take Gibraltar for exemple. His is slow and huge as well, but he can shield himself and an area, wich allows him to compensate fopr that. Caustic has none of those.
The urgent thing to change on him is this point : His gaz affects his allies.
I get it it is cool on an immersion point of view, but this is a team game. You are not supposed to play solo. Even if he was, except for his gaz, he his handicaped on a pure 1v1 fight. Why in the world a character based entirely on spreading gaz is affecting his allies as well? I find it nonsensical.
The second thing is his passive ability. Really? He is not affected by his own abilities and other caustics, and that's it? well... This should be obvious logic, not a passive.
Here are 2 things that I personaly think should be good to consider.
first, remove the effect on allies.
Second, add something to his passiv that can justify the fact that he is just a punching ball. Someyhing like, whan he fall down, he is emiting a small ammount of Nox gaz arround him. Not too much, but just enough to cover him a bit from sight and discourage people to just come in and finish him. This is not much but there you have it.
I don't think touching the gaz in itself is a good Idea. Upping it coulb be bad for the game and I will be affraid that he'll become OP all of a sudden.
Thanks for reading.
