I was actually refering to why I don't have a side character, and instead play as who ever I feel like.
as I play all the other characters, I learn what kind of combos they can do, and how they function in different situations.
another example is if you play against (or watch) the same person play the game over and over you eventually pick up patterns in that persons game play. This leads to being able to predict what your opponent (aka the person you are watching/playing) is going to do before they actual do it. (kind of like chess) It is on this idea that I believe mind games have originated from.
so you can apply it to the future war. (yes)
