ET is a cooldown that works in a completely different way when compared to Divine Seal or Assize. Emergency Tactics transforms Succor into a heal comparable to Medica and Adloquium into a heal comparable to Cure II (when it doesn't crit, of course). If Succor, with its built in shield, worked like a regular heal, there would be no point in being able to use Emergency Tactics with it. That fact alone proves that Succor is different than Medica/Helios and it also proves that ET does not make Succor a stronger spell (it makes Succor a different spell); Divine Seal, on the other hand, enhances all healing spells and is a completely different cooldown. Using Divine Seal and then casting a Cure doesn't prevent you from using it with Regen. Using Emergency Tactics with Succor puts the skill in a cooldown and, for the next 30s, you can't use Succor to get the same effect as Medica or to transform your Adlo in something comparable to Cure II. That's how SCH works: a healing decision either reduces the amount of other actions you can take or prevents you from doing any other actions for a set duration. WHM doesn't have this kind of restrictions, and this is one of the reasons why it's stronger in healing. A job having weaknesses doesn't mean it's bad; weaknesses have to be designed, they're not flaws. And again: ET merely gives the SCH something the other two healers have all the time, so it's not empowering at all. It's a gap filler. Deny that all you want, it's not going to change anything.

Also, saying that Embrace has 300 potency but scales less it's equivalent to saying it has a real potency of 200. Semantics won't change that and clinging to the tooltip is not going to make that skill stronger. Embrace is comparable to a Regen nowadays, unless you burn a cooldowm to Rouse your fairy for a short duration. I don't know why SCHs are trying to cover that up; it's not needed.
