to me i love being able to level multiple classes to get the skills i want off each to make a character the way i want it. as far as class uniqueness why not just do it like luminous spire for example is bought by guild marks and is only available for gladiator. by adding more skills/abilities that are earned by achieving guild marks in that class and only allowed to be used as that class would improve the uniqueness of each class as it stands. if you buy an ability for a thm through the thm guild and only the thm can use that ability then the thm will have unique abilities and people would have a reason to use thm. i do not like the idea of scrapping the current system because people put in the time to level the characters the way they want to play them, but i would love to see more abilities that can only be used by a certain class.
