As you can obviously see, Sehira doesn't want "hybrid" gear she just wants better gear. And yes "hybrid" automatically means weaker then specialized, its in the fcking definition.

Ex
Ring 1
INT +10

Ring 2
MND +10

Ring 3
INT +5
MND +5

All three rings have +10 to stats, two are specialized while one is a hybrid. There is no circumstance where you would equip Ring 3 over either Ring 1 or Ring 2. If you were not allowed to instantly change gears in FFXI then there would be a very strong argument for "hybrid" gear as you would be forced to balance out your gear prior to engaging in combat. Instead what Sehira is really arguing for is (and trying to hide it),

Ring 1
INT+10

Ring 2
MND +10

Ring 3
INT +10
MND +10

Where in there would no situation where ANY job would chose to wear either Ring 1 or 2 over Ring 3. Ring 3 is simply better in all aspects then either Ring 1 or 2 and thus obsoletes them upon its acquisition. The inventory+1 is just a happy side effect. And the moment you allow non-RDM jobs to equip that gear, its no longer remotely "hybrid", its simply the best. The conclusion to this line of reasoning is that Sehira desires RDM-only super gear that has better stats then all current gear put together. It must have better melee / WS / nuking / enfeebling / buffing / tanking stats, or some combination therein of all currently available options. AFv3 is good, but no job got gear like that. Everyone got amazing gear, but all the "hyrbids" got gear that was spread out a bit. BLU's head / body / legs are amazing TP pieces, but their hands / feet are nuking / s.blade pieces only. The "set" can be considered "hybrid" because the pieces are not all focused on the same thing, but each piece is specialized. WAR is the same way, feet / legs / body are TP pieces with head / hands being WS pieces. The legs can also be used as a WS piece depending on what else you have access to. RDM got a pretty good set, each piece is amazing at what it does and put together with our other casting gear is pretty amazing. Its all pure casting gear but at least each piece is specialized, no more DEX +5 CHR+5 parry +3 stuff.

And ultimately inventory is not an issue, ever. You don't need all the staves in a melee set, you don't need most of your casting pieces. A TP set, a WS set or two (Dagger vs sword), a full +enh set and some +Fc gear. The only "mage" gear you need is the big +enf pieces for sleep / bind / grav, you won't be doing maxed out Slow II / Para II while in melee mode. You might include a few -PDT / MDT pieces if your tanking things, that is a situational set. RDM worked at 60 inventory spaces, it can most certainly work at 80. All the complainers did was find 20 more "situational mage" pieces to stuff in those 20 slots, the continue crying about inventory.
