WHM DPS needs to stay this high.

[Hustensaft]

The 800 DPS difference between WHM and SCH is mostly made up by Chain Strategem.

The 2300 DPS difference (at max) between WHM and AST however... according to calculations AST provides 450 rDPS from Divination and 796 rDPS from cards at best unrealistic RNG which would mean over 1000 DPS difference remains.

Chain Stratagem doesn't even remotely make up for the 800 DPS difference.
