I think that FFXI is limited to 80 inventory spaces and there's nothing they can do about it. Something about PS2 limitations as per normal. They've got around this somewhat by using mog sack/satchel.

But yeah, I agree that carrying 8 staves all the time is excessive, perhaps something in the Magian trials line will alleviate this in the future or even add 'All affinities: +6" or something to Hvergelmir/Claustrum/Laevateinn/Tupsimati to make these staves worthwhile.

I'd also like to see a quest to be able to trade all your sea obis (if you have all 8) for one 'super-obi' which works on all days.

I also agree on the job changing thing. It takes forever to swap gear around when you change job, not sure if they can do anything about this though.
