In the last time around I hated running my lower level characters around Smuggler's Rest because you always had level 20's running at top speed through the place spawning mobs much higher level than the people in the area could handle. The L20's weren't stopping to fight what they spawned they were just increasing the frustration level of the player base that was already there. I went in this evening hoping to be greeted by an instance level dialog but it looks like the same playground for the big kids only that it was before.
So how do we keep the lower level players from getting frustrated and quitting?
