Interesting set up in the location of the dungeons on AL. There is a row of dungeons South of the drop that increase level requirements. Seems like it is set up to jump from one to another as you PL yourself. I am still using the Habitat and Quarters to PL my rerolls. Once I hit 50, plan on going to Armory.
Not sure how I feel about this set up. It is convenient yes, but I think it does take away from the overall experience of the game. I guess since there is very little new blood coming in, Turbine is providing a place to get rerolls up in level quickly(as long as they are melee or archers -heh)
