Honestly, I hope not.Personally, I dislike the fact they flat got rid of Shell as its own spell. Yes it was merged because its simpler, but there was always something that made you feel good in XI when you saw the Pro & Shell animation ticking one by one across your party. That being said, I would rather see traits that effect your subjob abilities. Most jobs have a select few abilities that they gain access to via their cross-class. Paladin is not the only one who is stuck with less than stellar spells and some Jobs/Classes could use traits that change/buff/etc to make these abilities more fun and useful. Traiting Pro/Shell would be a step in the right direction.
Yet I would like to see traits that enhance abilities specifically for their use on other Jobs. Having a trait that changes Cure to cost more, produce more threat (1:1), change its potency to be effected by attack power (like the change to Second Wind), change the cast time to be faster to allow for movement and change the recast time. The spell can be the same but function in a manner that allows it to be an intricate part of the Paladin kit.
The real problem is that unlike the Physical classes, the Magic classes really have some of the poorest cross class abilities available for other jobs. Summoner and Scholar are stuck with CNJ as well. Scholar gains... a poor version of Protect just as WHM does. The rest are spells they already have in other forms. Want Raise? I already have Resurrection. Want Cure? I already have Physick. Want Stoneskin? I already have various cure's and abilities that give damage absorption that are more efficient in both resource and time. For Summoner what are you going to do with those 4 spells when your main goal is to do damage? Aero you say? Maybe... ok, but if that is the whole purpose of CNJ for SMN ... give me a break. Allow some of these to have Job traits buffing them and we may have something.
