Since arena allow gloves, I think reasonable to assume rated bg had it too. Rocket boots and parachute would not be allowed.

In all honesty, I just don't see rated bg gonna fly. Not just for boxing, even solo, too much trouble, too little reward. Can't even get together 5 people to do things, let alone 10 or 15. For the normal guilds, they don't even do arenas, what would make them start doing 15 ppl organized pvp all of sudden.
