BLM is fine. Damage potential is high, but RNG tends to balance it out. People tend to forget that BLM damage, while spiky, is slow when RNG is unkind. The rotation is simple, but being able to anticipate correctly separates good BLMs from the rest. Poor positioning and timing is extremely detrimental since entire casts or vital procs can be wasted. Can't just duck out for 1 sec and immediately resume your combo lol.
