When you hover your mouse over a stack of your army, it shows units and att/def of the stack.
But the attack and defence points are calculated without adding general and strategy bonuses.
I always find my self in a situation where i calculate attack myself and it can be quite hard. Of course that shouldn't apply to your enemy because
you don't know his upgrades and strategies.
I suggest you make this update, I hope i interested you with this idea.
