A lot of them also tend to be douches too :/ then again, that's just how online play is. I have played some pretty good Rigs though.

Fighting a mashing Rig on a <1> connection is a nightmare lol.

I don't know what it is that makes them douches but a lot of times they are. My theory is they're trying to emulate his personality. Like one time a laggy Rig was dominating a lobby and saying shit like "pathetic" between fights like who do you think you are lol
