Are heal triggers even worth it in D Standard?

Power scaling goes up way higher post G3, making early guards some of the most viable guards.

On the other side of the coin, so much shit has rush them sooner than later as your only viable solution, which if it works turns off your heals.

Heal triggers don't even have 20k base shield anymore and the effect triggers are conditional enough for a lot of decklists to choose vanillas.

You can potentially be screwed out of counterblast you needed from heals actually going off.

I'm just not feeling them anymore...
