Evasion is a tactic far from retreat. Ive read the Art of War myself, and I find it funny that many people who like to quote it have not. One of my favorite lessons from my interpretation is quite fitting in this context. It bascially sums down to if you know your enemy and you know yourself, you will fight your battles without danger. That is why we are able to take you out while you have superior numbers. We can predict who is going to play what role based on who TNT has on at a given time. We know which players tend to stray from the pack easily and which ones are going to be the most devasting to the opposing side to lose early.
And if you take, "know your enemy," to heart, then you should know better than to assume I haven't read it.
Since you are so familiar with it, you must know that it is older than the New Testament. Just like the New Testament, it is impossible to quote. We can only quote translated interpretations that are 2000+ years old. Therefore, it is futile to argue over one word in a supposed literal translation.
More importantly, both Webster's and Roget's acknowledge that retreat and evade can be synonomous when used as a verb.
I'll bet I'm one who is considered to stray from the pack easily. Probably because I find challenges fun and consider this to be a game. A game, not an actual irl world war.
I seem to remember the last big fight, with you running right back into your West Luna house.
