True. I mainly kept it on my bar for Hellfire and Memento.
But now with the WS combos sometimes requiring the DPS players to attack from the side, I've sometimes found myself caught in Ifrit eruptions with absolutely nowhere to run because they appear both under and behind me (DPS players no longer stay right behind Ifrit). Sentinel can literally be a lifesaver in those situations too.
The effective duration is so short that it's really only good for those sorts of "imminent danger" situations anyway.
