I have 101 ranks in Shield Use and 35 ranks in Armor Use as a Cleric.

There should be SOMETHING for us (and everyone else) with that kind of training. Pull from existing skills, or add some new "generic" ones (that Warriors/Rogues/Paladins would also get).

You're telling me I don't know how to shield bash a target? Or adjust the fit of my armor to do something better?
