The core issue with Healers is variety, not balance.

[Risvertasashi]

Everyone brings up pets but its like no one has actually tested how much they heal for.
What ever pet skill potency says it is, you have to divide it in half. If you literally cast a pet skill that is suppose to have a potency close to that of a spell form an actual player, you will see it literally heals half on that amount. for example, embrace is 250 potency and adlo is 300 potency. when you heal a target with these comparable potentiates the embrace heals for less than half the amount its potency would lead you to believe. My adlo heals for 5000 at 300 potency, my pet heals for 2300 with a potency of 250. if you have a hard time with math 300-250=50 potency difference. but 5000-2300 does not = 50 potency difference. thats literally 50% lower than it should be.

You're incorrect - it's a 2/3rd modifier, not 1/2. In any case, 480 potency is the most powerful regen effect in the game, even after 2/3rd * 480 = 320. WD is still strong. Embrace is still strong because it's a stronger-than-regen regen that never takes a GCD nor MP and just happens, etc.
