Looks like some devs love Fight Club! Good thing, because so do I :D
Yeah. Also it's squeezing the sock.
I think the problem is the spectator mode, Blizzard wants us to watch but can't do the technology for us to watch like in Guild Wars 1 (still a fantastic spectator mode for the time).
The way around this is simply.
1) group, people join and the raid group etc get to watch. Everything's phased.
or if Blizz wants to keep the spectator mode open for everyone.
2) Have a series of quests around the world about joining brawlers guild (much in the way of the old riddle quest you got in booty bay pirate ships)
Then you enter, everyone can watch. You have to go to the brawlers Fight Club (it's what IT IS), to join up. Then you can go and quest and do what not until your turn.
You refuse your turn, you don't get a debuff for 30 mins. You're not allowed to re-enter the brawlers guild until the next day.
done and dusted. see that wasn't hard was it blizzard ;)
