Well I have 5 70+ jobs and don't skip on any of their gear, and don't really have space issues since the expansion came out... let's examine.
80 Mog safe,
60 inventory
30 mog locker(so 20 more potential if I need it)
4 storage(won't even bother counting cause they are all 1 soace storages)
So clearly with storage and mog locker upgrades I could increase my space, if I needed, I don't.
4 spaces for toolbags(Shihei, Jusa, Kagi, Sai)
11 loose partial ninjutsu stacks, 4 above, 1 for each elemental
3 Nin body pieces(not counting AF, though not stored cause will count later)
6 rings(snipers, flames, breeze)
2 hands
haidates
Full AF sans feet(upgraded to +1, body itching to get tossed)
Suzakau's Sune Ate(itching to get tossed)
Af2 feet, body
Evasion torque, Chiv chain
3 belts - swift, scouter's, warwolf(steppe too if I really wanted HP)
boxer's mantle, forager's mantle(gigant mantle same as above, really for pld)
eliusive earrings, melody+1s, rse2 earrings(+str, and HP). diabolos earring

3 mage-meleeing weapons
access to all my nin's acc gear(opt hat, snipers, diabloos earring, swift belt)
access to some of my pld's str gear(rse2 feet, hand)
weskit, demon+1, errant body, astral earring, loqacious earring, rse2hp earring(to offset astral on my smn)
ele torque, uggalepih pend, smn torque, fenrir torque
moldevite, abyssal
4 pieces of elemental magic swap in(af+1 hands, earring, legs, head)

rostrum pump
then I've got 3 swords for my pld, a gsd, access to the terra and pluto staves, all the rse2 earrings cassie, gigant access to all the nin's attack gear, af2 legs for attack, Some W gear, koenig, af+1, a spare af+1 upgrade piece, a shield a bow rse2 belt, shared warwolf with nin, access to vermy
spare junk like echos, silent oils prisms, some teleport rings, reraise hairpin, flee boots,
4 sea jailer pop items,
3 chips from tenemos
stack of ancient beatcoins
several stacks of seals
a lose bcnm40 orb(BCNM40 anyone?)
several pieces designed for Nin/blm(mostly borrowed from BLM, some from nin af2, asttute cape, ext, ninjutstu torqque/earring stored)
-random low lvl gear for capped shit either muled or in storage npc as full set, I've completed CoP so never an urgent need for em)
I keep all that shit, I never have to mule. I have over 10 free spaces usually unless I build up on crap from exping. I could increase my storage 30 easily through expanding mog locker and more storage if I wanted to lvl another job.
So when I hear people with 2 or 3 jobs saying how bad they have it on gear, I think they must be somewhat disorganized or carrying with them stuff that should be muled cause they won't need easy access to it.
I can't think of much except a few pieces I'm working on, and I can think of several things I can toss and probably will to make way for the new stuff. Even the AF2 pieces I'm hoping to get(like BLM AF2 head), replace things I already have(elite berit+1)
All this being said, every job has swap gear I rarely or never use. Beyond a few pieces in every slot it becomes very diminishing returns.
It was getting very bad before the age of mog locker but it's time now to stop using excuses we mostly know aren't true.
But all this is a tagent. Some of you posting here KNOW you're better off with the cheap stuff you've discarded. What I find funny... is the people... who think they kick ass without it...
