The easiest thing, isn't always the best thing to do, just saying Mordanthos.

A ability like provoke that is for the pld job (not as /war) would work better, as just making Provoke better wouldn't help pld, and hurt it more (more reason not to use pld if it can work just as well for other jobs)

A provoke like ability that allows all hate (or most) from party members (within range) to be transfered to the paladin (Think of it as a AoE of Accomplice and Collaborator) and make the recast time as 30 seconds like normal provoke.

That way a pld/war can normal provoke and when it loses hate control it can use this new ability to transfer the hate back to itself.

and I really think they should just make Cover a job trait, since it being a passive ability would allow better protect for the party without having to worry about recast time or other issues

(Like As long as the paladin is infront of someone who has the most hate in their party, they can cover them.)
