So even after the update, and proposed patches up to 1.22b WAR remains the only job that can truly dual purpose, does that continue it on the path of OP?
What I mean by this is:
With the switch of a stance a WAR goes from competent DD to competent Tank and back again. No other job can do this, not truly, I've seen/heard the argument that any job can tank, ok so they can, but I mean actual tanking, not "wonder if this can be done" 1 time tanking like ppl did for whm and blm to show off.
MNK maybe w/ some minor adjustments, eva buff during FoW enough to actually dodge Primals, a little more def in FoE.
DRG ... yeah that'll happen, gimme a pet I can stick between me and the mob
PLD gets tanking, assuming these patches give enough, but still not a competent DD
BRD I can't say alot here, I've only seen one play and it's a friend in my LS we grind together on PLD and BRD, I'm the PLD, and the dmg is impressive for a support job, but we're both only 40s and not geared for EG so someday I'll get to see it up close from a friend.
WHM and BLM I'd leave out, but let's face it, they can both DD well, BLM sublimely.
Guess WHM also fills as a healer don't know if we'd count it as dual-role though.
