Odds are we'll see things like Provoke, Protect, Stoneskin, and Quelling Strikes, removed from their respective classes, and instead be made into Role Skills. The classes that had those skills will either lose them entirely, or get replaced by something else (likely the former). Other skills, like Surecast, are probably going to be removed entirely since I cannot think of many times I've used it on any DoM class, let alone the parent THM/BLM. Given that they mentioned pruning abilities, I'd be willing to bet that the skills I mentioned first will be outright moved to Role Skills and out of their respective class' skill list, and the rest of the skills get their level-requirements shifted around a bit. That said, I'd also imagine a few brand new skills will be added to the Role Skills list such as weak defensive cooldowns, like Foresight, being made into Role Skills, or a skill for casters that lets them cast while moving at a walking speed (which would be awesome, and I fully acknowledge that it will most likely not happen...sadly).
