/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 arse" 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.
