We need mid-combat gear swapping.

I honestly doubt you get close to thousand.
Also, since we are talking about carrying armor around everything except your armor and inventory slot instantly does not matter.

You actually do get about a thousand counting all of those things
Personal Inventory = 100
2x Retainers = 300 (150 slots each)
Armory Chest = 300 (12 x 25)
Armoire = ???, but you can currently hold a decent amount. I currently have.... 222 items stored within
Shards/Crystals/Cluster = 18 slots

That all amounts to... 940 slots. Not 1000 but you can probably hold more then I do in Armoire, and I'm not counting key items /retainer crystals. That also doesn't count things like minions/mounts.
