1) I ran her through Bloody Gallery on a Rogue 47/Priest 47. (She was a Scout 27/Knight 23.) The first time we went in, the bats were respawning really fast. (As in, we'd turn a corner, and the bats behind us would be back.) I don't remember respawns in instances, and really don't remember them coming back that quickly.
BG is now a world instance that is open 24/7
2) We had to leave BG and come back. When we did, there was another pair in there. They were not part of our party, and we did not go in with them. We just came around a corner, and there they were. I thought instances were party-only?
again, BG is now a world instance.
also, are the "SW" results "siege" war, or "guild" war? guild war results are broadcast to the entire server...
