In case you didn't see it. :p
Upper tiers of an action (such as Fire II and Fire III) will be abolished in favor of a system wherein potency and MP cost are scaled based on the player’s level.
Fifteen actions and eleven traits will be made available for each class up to level 50, with either one action or trait learned for every two levels gained. Job-exclusive actions will be made obtainable via quests and treated separately.
Not being bound to any class in particular, the shield skill has been handled as an irregularity when it came to the obtainment of experience points and actions. In reviewing the identity of each class, it was decided that shield actions should be made a part of the gladiator arsenal. In order to streamline the system and accentuate class uniqueness, the shield skill will be phased out and instead take the form of actions and traits learnable by gladiators.
So @ 50:
1-You'll have 15 Class abilities, 11 traits and 10 slots for cross class abilities.
2-Tier of spells (and maybe abilities) will be abolished and instead the ability will get stronger the higher you are.
3-Traits are now class exclusive.
4-Shield abilities are now exclusive to GLA.
5-No more getting traits with tokens.
6-Can't unequip main class actions but can move them around in the action bar.
