What is a target AC to hit to be an effective tank. I know there are tons of "buffs" or other temporary effects but what should my unbuffed ac be after equipment, feats and enhancements. Right now at level 16 Pally I have 42 with sword and board. Currently I am KotC however I have all the feats I need to go Defender once the rest of my gear will saport being the tank. How close am I?
