[dev1206] Too many class-exclusive actions

[Atlas]

Exactly, I dont wanna be foreced to lvl a class I dont enjoy to 50 for that one ability that is "required" for xxx fight.

Also it may make healers need to heal DDs rather than heal the tank only and DDs have to heal themselves, depending on how gimped cures are cross classed.

If you're talking about the upcoming changes, I think they mentioned the skills' potency will be scaled based on the level of your active class.
That's also why they put the limit to cross-class skill at 10, I think.
