Soteria and Recitation are actually comparable from dungeon/tank-perspective,

Soteria results in 1156p. Recitation+Excog is 1200p.

The intent seems to be shoring up that equivalency.

Zoe is selected as the Deployment Tactics equivalent as they are both gained at the same level, have similar purposes when they are picked up (very close in potency when comparing Zoe+E.Prog to Adlo+Deployment Tactics), and gain their cooldown reduction at the same.

Recitation may be more versatile in terms of Adlo/Aetherflow, but Zoe works with the SGE’s 90 Pneuma.

It’s not a satisfactory explanation, but I think it’s the best to understand what’s going on in the developers head (no matter how off it may be).
