Idea: Making Card Diverse and Reliable (Less RNG)

[Bobsmiaw]

Why would I ever want to use an umbral card? Even if the mitigation is bonkers OP, each card that doesn’t prevent a lethal blow or GCD heal is a card better used for DPS, which they will all be because amongst the tanks and healers we have enough mitigation and oGCD heals.

What you said is true if every one in the party know how to play their job and avoid unnecessary damage (especially tank and healer).
In a different situation (PUG, new player, undergeared, etc.), umbral card can be a better option for survivability.
We have to make a decision between offensive buff or defensive buff because you cant use everything.
This will make AST gameplay more interesting and showing more of its support side (not restricted to only boost DPS).

Maybe you have other idea to address this?
Please share it if you have one.
