indeed. Its all depends on where the "pros" are in the teams. A goon can pwn a chainsuit, if he is alone. Even a skilled suit (not pro though). Its one of the most universal casses on aliens, also taking that the dimensions of it are close to humans, so they can get pretty much everywhere.
The only thing to know is:
There is no crosshair, you can make it with HUD mods, or with a grain of salt in mid of monitor, whatever suits you. (I play without it, no need).
The chomp angle is quite narrow, unlike tyrants. Its about 20-30 degrees from the line of attack.
And also, if someone is trying to tell that unlagged favours humans, this is so not true, if you play on unlagged, goon headchomps are easy.
