I am on the fence on getting a new retainer, I have all my combat classes (bar my melee's) at 60 and that saved me a lot of space because I don't have to cart around levelling gear all the time, but I have gone on long without needing another retainer so far, but if I am going to be levelling my crafters/gatherers, I might need the space.

Tbf the only reason mine are full is because I hoard a motherload of fireworks and glamour fodder, should probably trim the fat.
