SCH needs help

[Lilseph]

If you use one AF on Sacred Soil, you lose on using Energy Drain (150p).

Ok sorry but, genuinely curious again. If the 150 potency loss is that significant, wouldn't it be better to just not use it and let your co-healer use their mitigation tool instead? Genuinely don't understand why this is an issue.

Assuming your cohealer's mitigation tool is available, does not need to be held for a later mechanic and more efficient, then yes you're better off not using SS, and let your cohealer use theirs.
Use the most efficient skills first.

This is essentially an optimization issue; you want to use the most effective healing/mitigation skill given the situation to maximize your party contribution.
But I was mainly replying to those saying that SS is the "best" healing/mitigation tool available. It is very good, but not without its costs.

In my opinion the best healing tool in the game is AST's Earthly Star (low-ish cooldown, huge heal, DPS gain without overshadowing the heal), and the best mitigation tool is Reprisal (low-ish cooldown, costs nothing to use, solid 10%).
