This list is crap. If you, as an archer, see two people with equal skill and equipment fight, you should always shoot unless tehre is a better target around.
Reason? if there is a bigger chance of hitting the enemy than the friend (which we assume since the archer aims for the enemy and is hopefully not a total retard), it will statisticly help your team, increasing he chance of winning.
Same goes for lancers in terms of lancing and bumping.
What kind of logic is that? This is not about statistics, this is about humans, and I think all can agree that getting tk'd sucks balls.
Btw, if you really wanna go down that route, you're still wrong.
If I fight in melee, and notice that enemy archers are firing at me, I will ofc adjust my playstyle to that. I will twist and turn in time with their volleys and try to position my enemy between me and the archers. Also, I will play on the defensive, so that if I do get hit, I'll probably not die to my enemies next swing. Point being, if I see it, and expect it I will do my best to defend against it, vastly incresing my chance of survival.
On the other hand nobody expects
the spanish inquisition a friendly arrow in the back, and as such they are much more likely to get me killed.
