isn't that most of the 4th jobs tho, being used mostly for the new buffs? Classes like cardi, troub/trouv, bio, mies, dk, etc are just there for the buffs/debuff, heck dk barely has any usable skills unless they're spear/db/aa type. Only class I can think of who uses 4th job skills offensively are the shadow x (if counter slash build), wh, and possibly arch mage. I won't deny tho that the other classes do use the 4th job skills to gain ap, tho its either just the biggest ap gaining skill they use.
