Your ability to not get a group in stockades, and boosting really have little to do with each other. If people wanted to run stockades they would, they don’t, people would rather level outside of stockades.
There is almost nothing of value inside that instance and the quests around it are poorly designed so its difficult to pick up the quests for it at the appropriate level. Its simply easier and faster to level outside of stockades unless your getting a boost. That wont change.
Its really one of the big problems with classic/vanilla, most of the instances were poorly designed and poorly positioned level wise. This one in a lot of ways is near the bottom do to the trash loot and quest issues.
