How often do you use sacred soil?

[Klive]

SS scales with damage over 15 seconds.
Lustrate scales with target max HP.

(Damage over 15 sec) = y;
(Tank Max Hp) = x;

Set them equal b/c we want to be the same effectiveness to find threashholds.
y*0.1 = x*0.2;
y is our variable, you should know x once you have selected a tank.
y=2*x;


What does this mean?
Let assume WAR tank has 7000 HP. (Why warrior? I haven't tested how PLD DR work with SS. I can only assume.)
y*0.1=1400; y=14000;

The party must take take 14,000 (over 15 seconds) damage before a SS is worth using over Lustrate.
That is 166 (933 total) damage a second to everyone in the bubble. Titan and coil runs can easily do this kind of damage to the tank alone, let alone the party.

For easy thinking. Can this pull/fight/boss kill your tank in 7-8 seconds from full?
If no, then not worth using SS on JUST the tank.

Will this AoE do more than a quarter than the tank's Max HP to the people in SS range?
If no, not worth using SS.

Side note.
With you full DL tank, 1750 is the rough threshold of damage per person for SS. All primals easily cross this with signature attacks.
