I've got a Fighter / Cleric that I'm looking to do 12 fighter levels, the rest in Cleric. So I'm considering Improved Trip, which requires Combat Expertise. I hate having to burn a feat to get a feat. Right now, my Trip and Stunning Blow DCs are kinda "meh" without any additional boosters. I'm looking to maybe fix that with Improved Trip.
Is it honestly worth taking both feats?
And no, I don't want to add monk levels. Lets just keep it with the Fighter / Cleric split for right now.
