But as I was reviewing the abilities I still need to purchase for my various jobs... I was just left wondering if the new Jobs will have traits/abilities/skills that need to be purchased via guild marks?

If so, would Paladins be using Gladiator Marks?

I don't have the 'problem' some people in my friends do (like 40k worth of marks and nothing to spend it on) but I wonder if I'll be at a slight disadvantage if I don't. :P
