I've actually been doing really well this time!

But before the expansion I just blindly tossed or desynthesized everything that in my armory chest and not assigned to a gear set, so I've had more than enough room for a few sets of each gear/role type so far. I have four 90s so far (working toward doing all the role quests) and the main thing I can see being a potential problem is getting too much JSE before getting the tomestone gear that takes up less space at the cap. If I was focusing on tomestones instead of leveling, this wouldn't be a problem either.
