Yeah, the UI is poorly designed. Good thing they're making a new one for the PC version. Most of your complaints don't really have anything to do with the UI though:
Use the moogle storage slips instead, which don't require the full set to store.AF Storage
Really.. need to trade a full set and 1 of my pieces is +1 or I want my thf shoes only and not the other 4 pieces.
Use the storage slips.Salvage armor Storage
Can only set 1 armor set...
Really... Let us store all sets.
There's nothing "retarded" about the pages. It's not like they take actual space up in your inventory, they're key items. having the key item is simply the marker that tells the entry NPC you're ready to go. I see no problems with this.Meeble Burrows
Why retrade pages...?
Even getting the page is useless. Should just walk up and choose the objective and it should save everytime we complete it and reset after a boss.
Because they can store the items as flags on the storage slip, which requires less data space and memory. It also is a good way of bypassing multiple "are you sure?" dialogs. The only way this could be desinged better is if there was no ps2 limitations and we could just have more plain old item storage space.Porter Moogle
Slip page items... why do we need them...? Never needed it when I had to store AF or Seasonal Event gear. Why not just talk to npc and choose the gear we want back...
Honestly, I'm not trying to say these are the best things in the world, but it's really not rocket science or hard in any way.
