The weaponskills from the campaign weapons need to be available to the jobs that can use the campaign weapons. Uriel Blade in particular would be a great asset to plds. An AoE flash on a sword would not be overpowered in the hate department and pld already has Circle Blade for the AoE Factor. There is just no reason other than letting NPCs have something players cannot obtain (other than in campaign battle). Or at the very least make a 119 weapon that has this ability on it. An 'easily undertaken' quest, which would still be a lot of work, for this ws would be to do a certain number of uriel blades while in campaign battle. Starting from scratch and working off a 5 day re-eval deadline, it would take someone 100 days just to be able to buy the sword. For those of us that have been playing forever and already have a high medal rank we could do it quite easily. Which would make it a good nod to those of us who have been playing through all the content both recent and old. I'm sure this applies to other jobs/weapons as well, but i'm main job pld, and pld is the only one of my lvled jobs i truly enjoy.
Total side note: Crusade needs to be an increase in enmity cap, not an increase in enmity gain. I can see the point of not just giving any certain job an enmity cap over everyone elses, there may be an instance where you don't want your pld to have absolute enmity, but were crusade to be a hate cap boost it would become optional to have more enmity or the same amount as all other jobs.
