BLM should be the SAM of casters.

[AlphaSonic]

Sure lets not have BLMs bring along Mana Shift to help keep the healers mana up, or Apoctastasis where they can throw it on the tank to help them get through magic TBs like Exdeath's Thunder 3.

The best SAM can bring besides a slash debuff is Goad, which is only useful in AoE situations if you have another big TP consumer in the party, or feint which has a questionable influence on damage but BLMs get Addle as their version. So technically BLMs do bring as much if not more useful utility then SAM does. Especially since Leg Sweep is also useless on the vast majority of bosses.

You are so brave, thanks for sharing your story.
