Sure, you have diplomacy/bluff/insight to help you do little things...but because so much is left up to the DM, there are no real rules on how a social effect should work? How far is a person willing to believe a lie? How much can you manipulate a person before they start catching on? These are not really talked about.
To rectify this, I wanted to make a new form of power - The Social Utility power. They take up your utility power slots, but they allow you to work wonders when it comes to interacting with people. Here is an example.
Customizations basically work to make the power an Encounter power if you select one of the customizations to be added or a Daily power if you select two of them to be a part of the power.
This is currently part of my power pack for Fighter's which you can see here rpg.drivethrustuff.com/product_info.php?...
Would love to hear some feedback on this.
