there should be a map in the city like the coloseum in rome, where any one could go sit in the seats and while your waiting for a group to be ready u could watch pvp, having all the shops mail boxes, and trainers u could want right there. even betting (stormreach currency not credit cards) on the fights.
a waitng list so u could see the fights not have them just be spirited away while all u can see is a empty building. some kind of inpenetrable baracade so the crowd doesnt get nuked but can still see.
and clear fighter records the crowd can look at while watching to facilitate informed betting choices. fighters getting a cut of the total bets plus a little thrown in by the coin lords in case betting isnt as heavy as it could be.
