Okay. I'll run through every single level 60 Instance from Aetherochemical Research Facility up and through Burden of the Son (Savage). One at a time. I am gonna just lump dungeons together, because they all function identically.

Dungeons
- Trash pack - SS at the end gives you Mana for the next pack or the following boss.
- Boss - SS at the end gives you Mana to turn Grit on and Mana for the next pack.

So does waiting for 3 seconds for your out of combat mana and health regeneration...

Anyways, your examples are valid but I like how you go: "A little extra help." on some of those things. It really shows how little the skills value is compared to a real cooldown. If Soul Survivor had a much shorter cooldown and a (This skill can only be used at enemies below a certain amount of % hp) it would be a much better ability. As well as not being able to use it on main bosses, because as I said before.

Your out of combat, so your base out of combat HP/Regen is better.

An entire ability shouldn't justify by waiting a few seconds...

Anyways, it seems you have something against DPS healers. However a Paladin in level 60 dungeons can go full defensive and let the healers DPS, especially scholars and mass pulling making the zone a cakewalk that can be done in 10 minutes.
