the spells can be done any job /NIN.
I think Yurin is a proc isn't it? if not, yah, all can be done /NIN, But it'd be a b*tch and a half to land the Debuffs XD.

I think they removed Merit spells for the reason that they weren't very fair in the first place. I know a few jobs lose exclusiveness with it, but I merited 5/5 N.T.E and 5/5 Hyoton back in the day, I planned on keeping them.

RDM is hit the hardest i think. But RDM is already dead, So its like they're just kicking the body now.
