The arena was taken out for player battles due to abuse/bugs from what I remember...I think this would be a HUGELY good thing to bring back into the game, especially with the influx of new players we're trying to drive via voting, Arena has a lot of benefits for them.
I think it would also be awesome from a RP pov, how about Gladiator fights on a fri or sat evening - organised odds and betting etc... I'd be totally up for watching that, and maybe competing if I got a character who was right for it!
