To be honest, I'd like to see this 'math' of yours as well. Because, in case you didn't notice it, they merely increased the potency of their single-target non-DOT spells by 10 each. While I admittedly have not played a BLM and so don't have the kind of experience with the class that you obviously do, I feel as if this isn't enough of a difference to make them the kings of Single-Target AND AoE DPS.
