My experience with dragoons: they die to everything in Ramuh. I keep stoneskin/adlo up on them, especially during add phase. Shiva is not so bad unless they screw up a mechanic. Nael, megaflare I adlo the dragoon because sometimes succor is not enough. If I'm on my WHM I make sure they have stoneskin up before anyone else. Final coils, our dragoon switched to main ninja so I have no experience with dragoons in FCoB but with all the magic based attacks that are unavoidable I think it would be a nightmare to keep them up. I know my friend's group has a dragoon and he dies a lot.
