This is a silly exploit that is good for being annoying. Join any raid group, then join an arena. Get leader of the arena team and it will also make you a raid leader in the other group you're in. This will last the entire time you're in the arena. Unfortunately you cant really do much with the raid but you are able to spam raid warnings and such. Again, nothing major, but fun to play around with.
Now the fun part is when you become raid leader, you can change the loot options around so that you can ninja loot! Thats if you dont care about your rep.
