Life does not equal tribalwars; if you are expecting kindness from others in real life, I'd applaud you. I expect it as well.
Do it in a game where the object is victory and the margins of obtaining it are small, and I'd take every advantage over you I could find.
Theres still a lot I would debate in your post.
However to avoid the thread getting to messy I would have only this to say about honor and TW in reference to your post.
I myself almost see it as the reverse of of what you suggest, or at the very least have a differing view that shows the differing approaches between players in regards to honor and the way the game can be played.
I live and work in a rl world where I feel the margins of obtaining "victory" are slimmer, and especially in my work life have to be pretty hard nosed and ruthless. In TW I get to be in the top few % but I get to do it in a way that doesn't need me to consider screwing people over to get it.
I think that you are verging on the argument that you can not be successful at this game without at times being dishonorable, or indeed acknowledge the fact that morality has a part to play in the game at all. I still dispute this and maintain that a strong sense of morality or honor can actualy benifit you as a player, especialy when you take multi world players into account.
