Hey everyone, recently I tried building a hybrid avenger/wizard (haven't played them yet mind you) I went hybrid avenger mostly to use the avenger's armor of faith talent thing, and the point of the build was to see if I could make a character with a similar AC to my friends level 1 earthstrength warden (AC 20 Fort 16 Ref 12 Wil 12) which he will be using in an upcoming campaign we'll be playing. So I was wondering how I could modify the defenses of my Wizard/avenger to make it better, like is higher in one defense better or relatively even in all? Also any advice would be highly appreciated on other parts (especially powers).

p.s. The reason it as a Guardian Staff was because I had thought of getting the "Superior Implement Training (Guardian staff)" feat at level 2.
