Just a bit curious. How would the strengths and weaknesses come into play? Is it simply rock paper scissors, or one faction would have the advantage in a certain situation?

It's an advantage in certain circumstances, like a tactical advantage that may tip the scale if there was a conflict on even grounds. Though just because an Angel is strong against Demons, doesn't mean they will win when fighting 2,3,10, or a hundred Demons. 

Think of it like the advantage that may come from having better terrain, numbers, morale, or positioning. It will help you, but it is not a guarantee.
