Why bother with recruitment? Anybody with enough interest would notice a tab that said "Arena". That's what I did when I noticed so many years ago. I went by a different name then though- not like that matters or anything.

I think with all the power-wank that is the arena, everybody would rather be part of their own little faction with all the different characters they use being in that faction. Of course, there are people who have both "heel" and "face" characters. If nothing else, it should just be no factions, as it's always been. Who needs team work anyways?
