I think for the next little bit, lets go through small feats that will be power source specific, but add a little more of what I think each power source should/does focus on….
Quick Prayers: Feat, Choose one divine at-will attack power you know, that power gains the healing keyword and effect: one ally you can see in burst 5 gains 3 temporary hit points. This changes to 5 temporary hit points at 11 level and 7 temporary hit points at 21st level.
Throat Punch Games 
Good job Ed – this seems pretty useful and appropriate. I think there are some powers that act like this but the feat would help tailor a character more.to what they want.
