I'm a Pally right now. But with +1 Initiative, right at the beginning of a fight, I can teleport my Knights in the right spot to use the special sweeping attack on 3 stacks, and this before they can attack. So I usually kill 2 or 3 stacks at the beginning of the fight. With alot of +Morale +Def +Att on Knights, it's devastating.
I'm now using the Orc Veterans instead, with the special attack on 3 stacks.
