3rd Retainer by Default, please?

[Saseal]

As someone who would consider myself a gear hoarder that thinks in "what if"s...
I'd like to be able to hang onto old gear for future classes, but still have room for new junk that keeps rolling in. xD Old non-50 THM robes, etc? Toss it on ARC. Old ninja dex gear? Toss it on archer (and probably later, Machinist). Some of my old conj/WHM stuff went on my SCH - same with some of my MNK stuff on my LNC. Glad and Marauder kinda share, too. Same with my crafters! And the new classes coming out! Arf! All the mind gear on my AST! All my tank gear on my DRK! All my.... well, I don't know... dex and/or str stuff on my MACH! RECYCLE ALL THE THINGS! @o@ ....*taken away by the Eorzeans in white* I do turn some of my 'meh' or doubles into materia, but... I don't wanna spend money re-buying HQ gear or hunting Aetherial gear later for my noobs when I can just grab and equip it. (I was originally leveling all my magic using jobs just so I can turn the no-longer-useful-anywhere int/mind gear into materia.... and then they brought out news of the new jobs >.>)

Same thing with the crafting stuff.... "WHAT IF I NEED TO CRAFT----- WHEN I GET THE LAST ------- PIECE FOR THAT [insert fancy furniture/armor crafting item here]". *palmface at self*

...but seriously - I also have a lot of crap that I can't put in the armoire (I tried) - the 46785687 colored dragon/horse/rabbit/sheep helmits, earrings, etc event stuff (I just noticed they added all that to the cash shop, too o_o).
I'd love to put my old classic WHM robe stuff in the armoire, too, for remniscence sake (have to admit, the white and red is one of the iconic gears of the old FF games o.o).

I should probably just get a third retainer.... but I would so be down for a quest for a third retainer. I would do it in a heartbeat. I would throw myself at Titan EX for it. :| ....maybe not T5 (*hides under rock after the last bunch of attempts*), but I'd throw myself at Titan EX! (lost cause if it required completing FCOB though...)
