I would count Rapture/Solace as little more than Cure 2 or Medica, just with a DPS refund attached, so I compare it more to Benefic 2 in the AST example. Even with the formula, the heal potency does favor Essential Dignity more than Tetra from 50% and beyond.
At 50%, the Discrepancy is 900
At 30%, its 1460
At 10%, 2020
Also, if we're going to account for other GCD and oGCD tools in their respective toolkits, AST does have Synastry and Lightspeed so they could pump out Benefic 2 with a 40% potency buff vs a Solace+Divine Seal combo at only 15% but I'll admit the inclusion of Divine Bension and Protect would alleviate some of that difference until AST unlocks its equivalent skill versions and Divine Seal does have the benefit of boosting our AoE heals, especially with PI throw in to make Celestial Opposition's inclusion moot, WHM would probably be better off than AST in regards to AoE healing while AST would be better at Single Target, at least as far as the level 70 benchmark is concerned.
As for the topic of 2 stacks of Assize vs Tetra, I don't think we'll be able to resolve our opinions on that matter so I think its better to just agree to disagree there.
