Umm, seems to have no logic to it. How can you really learn anything if you never learn to know when to disengage? Like, if I'm in a fight on the deck with one guy, low E and all, and spot a 2nd and maybe a 3rd guy come in, I'll try to extend, climb, to try and regain the advantage if possible. If that's not possible I'M GETTING THE HECK OUTTA THERE!!!
What you are doing with that attitude is, a) never allowing yourself to learn how to watch your back and b) fight until there are no enemies or ammo left, or until you DIE.
I see no logic in it, other than it could be done by a AI just as well.
It's like... other enemies showing up IS part of the game AND part of the fight. If people don't want to adapt to the fact we have a DA and the MAs aren't it, it's not my problem really.
