According to FFLogs, AST pDPS >= WHM pDPS in 4.3

[Miste]

I know that SE, for whatever reason, doesn't like buffing WHM damage, but I think it really needs it at this point. It shouldn't be losing to AST and SCH in personal DPS at all.

If it turns out AST is doing equal or pretty close pDPS as WHM then yeah, SE really should give WHM some more pDPS by increasing their potencies.

I'd like to see more of a sample size from the logs first though like Ghishlain said.
