DMM is really only a problem when paired with large number of Nightsticks (for cheap turn attempts).
If one is limited to 1 Nightstick, one can DMM Quicken about 3 spells per day, or make a couple of spells Persistent (the most powerful use), which is very strong but not quite broken. But of course it might still be above the target power level of this game.
(Btw, this has no impact on my PC who doesn't use divine spells, I'm just discussing here.)

By the way, samduke, your sheet seems to reference a Metamagic Rod of Persistent Spell, but no such item exists (even if it did, it would probably eat up all your wealth...).
