BLM - Flare....do you use it?

[KomoChameleon]

So Flare seems a pretty underwhelming skill to me. The only time I can see it been useful is if you are AOE'ing mobs and you are nearly out of mana and want that final ooom spell. But even then I'm not sure if it would be ideal.

I have parsed and used this in my rotation in a number of formats, generally using it as I am just out of mana with swiftcast, and then casting transpose. But this does nothing for or against the dps.

So is this a worthless talent? Does anyone else use it for something I havn't thought about or in the rotation somehow?

Edit: I mean transpose instead of convert.
