To do anything they would need to toss out the current armory system.. Seeing how anything that uses a "1 handed blade" is a gladiator... there goes your thiefs and ninjas. But maybe thats just because i don't like the current system at all.
I just want to see unique classes, not bastardized hybrids. Though dragoon does need a wyvern. That is missing.
I'd like to see a clear cut:
Warrior
Dark Knight
Theif
Paladin
Ninja
Ranger
Beastmaster
Dragoon
Monk
Samurai
Black mage
White mage
Red mage
Blue mage
Summoner
Maybe some new DoH classes, have a "trapper" that can use traps on beasts to get items as opposed to fight... or catch them to sell to beast masters...
There are lots of possibilities... once the bastardized armory system goes away... far far away
