it's because you combo'd if you have a blm that is gonna spam flare you gotta spam flash>flare at least for me i have never lost to a blm who flares.

now also you can only do 2 flares (at full power) in a row after that you are doing ice flares which are pathetic in damage i was doing some sr's and had a blm do 5 flares, 2 full power aka fire 3 flare convert swift cast flare then transpose flare blizard flare transpose flare. which the last 3 did 1/3rd the damage of 1 of the full power ones, while the monsters still died fast it would have been easier to just double flare fire 2 them.
