Hmm actually what you're suggesting would work as a fix to the problem. If the extra weapon type is part of the Base Class there won't be an issue when swapping.. Why I didn't think of that before is beyond me. We just have to make it so that the extra weapon types are a trait that is specific to anything branching out from the base. Not sure 50 is the right level for that though.. should be earlier. Just a thought.

Obviously we give bonuses to players for using Great Sword (on DRK) and sword/shield (on PLD) to kinda curb their choice into something that makes sense.

I agree that 2 is a good number for specs. If they add 3 per base we'll be out of FF classes before we know it. I also agree that reserving something as diverse as katana is better left for an entirely new Base. lol

^ adding to OP#3. Lemme know if something should be changed from there.
