/Sam is what I find myself using most since Abyssea when tanking, DDing or triggering "!!" weaknesses, with the healers having asmuch refresh & enmity down as they currently do, damage mitigation comes in a distant second to killing stuff faster.
You'll still want /nin sub leveled for tanking the odd "pain in the ****" NM (Manananggal, I'm looking at you) that likes nothing more than eating your face, but you'll find yourself subbing it alot less than back in the day.
/Dnc as always is useful for solo stuff.
