because they never used one name for the other in the different FF games... just reading through this in a few games the normal protect spell was actually named barrier...

I don't mind if its named protect since at first it only does what protect does and until you get the trait it is only protect. Also if anyone takes this as a cross class ability it will only ever be protect...
