Pete,
I saw a reference one time that the instances worked like that (no respawns) the first time they activated them the alpha. It was set to its current status of respawning the general mobs (not the named ones) to try to prevent solo characters from just slowly grinding the whole instance to an empty state even if it took dozens or hundreds of deaths.
From what I have heard in terms of complaints about some of the end points (named bosses) in the instances; I was under the impression that they did not respawn as the general mobs do. This may have changed with phase 3, but I do not recall hearing anything about a change like that. Besides if the named bosses kept respawning every 15 minutes, would not the Scarlet Monastary have been mined for items even worse that was last push? Any pair of mages that went down to whoever was the favored one to knock off would have only needed to keep hanging around to pick up two or three kills to max out most of the variety of items that potentionaly would drop.
