What is the thought process of trying to decide on an optimal offensive build if I know the defensive composition? Do I look to balance my attack forces based on the defense (a mix of inf/cav/arch attack power)? Or do I look to overwhelm the weakest link in the defense and invest all my provisions into exploiting that? Just to provide some concrete numbers: I'm dealing with a 5k SP, 5k SW, 2k AR defense with lvl 20 walls. Berserkers are not available.
