It was added around Season 2 or 3 during an event. It and a few other skins like Viceroy Bangalore were added permanently. The entirety of this event will be permanent and will be available at any point for the rest of the game’s life, and will be reduced in materials price after a bit of time. The official patch notes don’t make it very obvious but they will indeed be there forever
These are the patch notes where it states they buffed him.
Yeah, nobody is going to stay in the gas that long. That’s the whole point. Now, people are actually punished if they stay in the gas too long and only morons try to push through it. And when they do, they get punished for it.
And no, having a flat 5 damage to downed players isn’t an “overall nerf.” The only reason reason you should be gassing a downed player is to stop their teammates from reviving them. If you want them dead, finish them or shoot them.
Since his buff, I’ve only seen one post complaining about Caustic, and it was from some brain dead streamers who want to rush their opponents no matter what. And iirc JayBiebs has said he isn’t going to listen to them, and I personally trust him a lot more than I ever did DZK.
Here is a closer high quality look at the new Caustic frame.

He's a murderous scientist, so it should be a calculated object. A canister would be so lame. The brass knucks are okay, but too 90s b-movie villain cheese for me. I'd much rather have a sledgehammer, ice pick, mace, or ball and chain than the knuckles, just because it would be more obvious and you'd be able to have more animations. A scalpel would also make sense to me, or even a rag he occasionally pours clorophorm (or nox) on.
