I agree regarding equipset's but why not level a job that is less dependant on equipsets like a melee job? Thf or Mnk etc - neither need more then 10 out of the 100 for equip sets and even then you can probably lower that number some. Its not like you need to make equipsets for every JA etc, that you can make your own macro's with thre equip you need macro-ing in, then the wait 1, /equipset x etc.
I would love a Mog Warderobe 2 more then more equip sets right now, Im stuck on just 3 jobs due to not wanting to start moving gear around when I change jobs, maybe I can do it, but I've got so used to keeping exactly what I need in the Warderobe and in inv I simply switch jobs without any need to swap gear. I'm considering other ways of doing it tho, COR for example is taking up more equip then MNK and SAM combined (and /equipsets lol).
I'm with you about loving /equip sets tho - I Even have a few devoted to /lockstyle because there are some very ugly equipment sets and mixes out there. I don't think some ppl realize how easy it is to create an equipset purely to /lockstyle for your job as you can chose pieces from any storage facility.
