I've got an idea: an area where no one can enter a fight on. It'd ensure more privacy, you know, if a level 1 "noob" nonchatter jumps in to a fight where you're trying to set a record off on? That'd ruin your almost-perfect video you were posting on Youtube of the highest damage. I know some of you will disagree, and I respect what you've got to say.
As greyrose said, just for specific like record breaking with youtube a gauntlet or dungeon would work.
But i agree i think if you enter a fight you should be able to block other people out of it. I especially don't like when i'm in celestia questing and doing one of those beat these guys and it will drop quest. And then you will see people that just watch as your doing all the work blading and everything, and right when your ready to kill they jump in so they get the credit to when you did all the work.
These places already exist in all worlds of the Spiral - they're called Dungeons and Gauntlets.
If you turn off teleporting, no one can disturb you while you are in a Dungeon or Gauntlet.
Thanks again for your hasty response, professor. Well, I was a bit unclear on what I meant to say. I meant, like when you're on a quest that's outside of a dungeon, it'd be nice if you could "lock" the dueling circle.
