I've had a few successful attempts with it but it is very situational because of the animation lock.

If a lot of people are dead during Ifrit HM after Hellfire phase (Some people have trouble avoiding plumes...) immediately run to the middle after he does his last tackle and use it. You should be able to pull it off successfully.
I was once in a party with low ilvl players who were doing Ifrit HM for the first time and couldn't dodge plumes well. Only me and the tank survived after people were dropping like flies and I managed to raise 6 people with the limit break and we all won
