I don\\'t play melee so I can\\'t comment on them.

However, I feel like for casters this issue arises from the fact that the role skill abilities they have don\\'t often fit with the job.
For example, Apocatastasis and Addle don\\'t feel out of place at all as a Summoner or Red Mage. But on a Black Mage, not so much. The same goes for Drain.
For a Red Mage who has Vercure, or a Summoner who has a tank pet and Physick, it feels very out-of-place.
As a Black Mage with no other means of recovering your own HP, though, it may feel indispensable in solo content (despite healing too little to be worthwhile).


And of course, as with all role skill pools, there are some abilities that are functionally useless, for casters Break is the biggest offender, as is Drain due to the low potency and healing it offers (for comparison, a Summoner\\'s Ruin spell is 80 potency, whilst Drain is 50 potency I think)
