Since weapon access has been something hinted at in the most recent trailer, I'd like to see some new or classical weapon selections added.
I'd like to see WHM get access to low delay Bows, perhaps a C Rank in Archery. Give them something they can add to a PT when buffing or curing isn't needed for a few rounds. And offer stats on the bows that make it worth giving up the ammo slot for.
Give COR access to crossbows, its a marksmanship weapon and status bolts lend well to a support class role. I'm not asking to access to Orthenus' Bow (though I would be sweet, but this would add a bit more to COR since there seem to be no plans for status bullet. It would also be nice because it woule alleviate COR's price tag a bit, status bolts are cheap.
Let's also get a new equipment slot we'll called "Held." Let's free up that Ranged/Ammo slot for jobs that can equip and use ranged weapons. It inhibits mage and melee classes alike from more options. A Bard can't benefit from any Ammo items because thier job requires constant changes to the Ranged slot. adding things like Orphic Egg that BRD can't feasably use is kinda insulting.
Give RDM some real staff skill, if they're supposed to be good "dualists" how come they are more capable with a sword they hardly use than a stick they use more often?
Samurai are reknowned swordsmen, let them access EX sword skills w/o subjob requirements. And give them something to play with between 50 and 70, their bow options are a wasteland there.
THF with access to Katanas would also be nice.
