Performance Mode in Instanced Areas

[piipiipii]

I don't think it's fair to assume the absolute worst of the community at ever turn. Yes, you're not in a duty to perform, but you're also not in a duty to use the bathroom or take your dog out, yet waiting for either of those things is a frequent occurrence. I don't think it would do any harm to be able to listen to an impromptu harp piece during downtime in a dungeon. If you wanted to purposefully grief in a dungeon there are plenty of other ways you can already do it.

Most BRDs have little to no skill at Performance.

Exactly, which is why the chances of seeing someone do it would probably be slim to none. I can think of several multiplayer games off the top of my head that allow for playable musical instruments in "competitive" multiplayer modes despite the theoretical potential for "abuse" because... they're fun. If your fun comes at the expense of others' time they have the tools to reprimand you for it.

I think it would be a niche yet positive addition. God forbid anyone have fun.
