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

[KDSilver]

Small easy fix since Ast has now more mobility and almost no clipping at all now.

Malefic III 220 => 210.
Combust II 50 => 45.

But what he's doing now is what he could have done since the beginning since no potencies have been increased.
But yes, that was an indirect increase. And his new mobility and new lightspeed allow him to cast more Malefic III.

I think it wouldn't hurt too much to lower a little potencies as I said if it really almost matches WHM dps, even if I doubt it.

Or just make Stone IV be 250 => 260.
