I agree with sammy here. Just playing around today, my ship took a double flamer pyra, and wrecked the whole game, with the enemy pretty much unable to do any damage to us. Also, being on the receiving end of a carronade and flamer, with a rather experienced crew, we still found it difficult and frustrating to try to recover, with every attempt of fixing the balloon ending with it being broke again, or more fire, which by the time you get around to being able to repair it after a shot of chem, the carronade can and usually will have the balloon broke again, that along side trying to keep every other component from catching fire.
I personally feel it should get a little more of a debuff, reduced damage to 1 and stack chance reduced to 15% maybe. Because right now the only time it usually destroys components is with ~13-20 stacks of fire and needing to fix/chem other things to minimize the number of components needing to be rebuilt.
