How much WHM DPS is enough?

[Mahkii]

That is kind of the silver lining. WHM+AST, with the AST main healing, could potentially be a good option for pumping out healer DPS.

Someone made a very detailed analysis here: Stormblood Healer DPS Breakdown

I think people will opt for the Chain Stratagem because of crit procs though. Examples: MNK Chakra, AST Lightspeed, etc.

Its also kind of a shame that the situation has been reduced to: always bring AST, now we choose between WHM and SCH

And so the question I pose for that scenario is, why not just bring 2 ASTs?

What you describe is why I think we're more likely to see AST+SCH reinforced even more than 3.4 & 3.5. I don't really think it will be a decision between WHM and SCH, truthfully.

But there is that possibility...
