I certainly agree. Red Mage is the only Discipline of Magic that is designed to never cast the same damaging spell twice in a row when fighting a single target. I consider that to be one of its strengths for making the job interesting to play, but unfortunately that style doesn't carry over into its AoE damage. My hope is that Tether will be replaced with a second AoE spell so Red Mage has something to alternate with Scatter.
I'm going to propose a slightly altered action list for Red Mage. Most of it is left untouched, but just a few small changes is all it takes to improve the experience.
Code:01 Riposte 02 Jolt 04 Verthunder 06 Corps-a-corps 10 Veraero 15* Displacement 18 Scatter 26 Verfire 30 Verstone 35 Zwerchhau 40* Moulinet or Red Magic AoE 45 Fleche 50 Redoublement, Acceleration 52* Moulinet or Red Magic AoE Displacement moved to level 15 from level 40. Moulinet moved to level 40 from level 52 or kept at level 52. New Red Magic AoE added to level 40 or level 52. Tether removed.
