I actually really enjoy the idea of this species, and it's also in the code already, so why not? IMO it's a lot more unique than the current selection, and with a bit of rebalancing [spoiler2]Remove the insane x2 brute and x4 burn modifiers[/spoiler2] it could prove pretty unique.
I just wanted to say that this suggestion isn't entirely shitpost. This symptom did actually really entertain me, even if it was completely overboard while it was still in the game. With a significant nerf, it could prove to be p cool.
