Caster weapon mogs

Actually kinda cringe that a lot of classes now can mog different weapons such as axes polearms maces
When using a sword as their actual weapon

BUT

You can’t mog a dagger to look like a sword and vice versa as a caster
Like what’s up with that?

yeah it sucks

I have a sword but i want a dagger model to mog. Can’t do it gotta do the sword!
