Those aren't mages though, they are just knights who use magic. And Magitek Knight? that's not a job, more like a role, specifically from FFVI. I think you mean Magic Knight/Rune Fencer/Spell Blade/Mystic Knight/Spell Fencer/Rune Knight

The only reason Dark Knights use MP over the traditional HP, is because they are a tank and HP is their main resource.
