On a side note, the tier 5 tainted scholar +2 dc ability sort of irritates me. For 3 AP, bard spellsingers get +2 concentration/perform skills, +2 spell penetration, +2 enchantment DC's, and temporary spell points in an aoe around them when they sing songs. Tainted scholar uses the same 3 AP and only gets +2 to the dc of their choice, which doesn't include necromancy (the only real choices being evocation or enchantment if you're going tier 5 scholar, anyway).
Yeah, I would just replace heighten with completionist feat.

I feel your frustration. I think bards are exceptional. Every other class has to spend 2 AP for 1 DC. But warlocks get 2 DC for 3 AP.
