SCH lacks a single target mitigation ability

This.
Sacred Soil is 10% mit and a 6*100 potency regen. It's especially valuable on double tankbusters, moreso now that SE slapped a bleed on them. It costs an AF stack but you get far more for your 100 potency loss than if you'd use a plain Excog or even Lustrate. The only thing is that it needs timing (and put your tanks on a leash) so you don't lack mitigation for an aoe that absolutely needs Soil.
But the gaps between busters and aoes are either fairly short so you can catch both or so far apart that you have it up again - if you need it because no point in slapping Soil on every wet noodle aoe.
And in dungeon pulls it's a no-brainer. Just throw Soil on every pull.

This, I’ve found that soil is the answer (for me at least) on double buster mechs that require both tanks need some love, normally this with whatever my cohealer is using is all I’ve needed easily deal with any damage, it also if used at the right time will last for any subsequent raidwide for the party.
