Honor Attacks

When it comes to attacking for honor, you can tell how much honor you will get when you click Attack. A window will show your castle name and your targets. Under that is a crown looking symbol. That is the honor you will win or lose. If its 0 or negative, dont attack. No use. I steer clear of any attacks under 20, as the smaller numbers usually arent worth it and they are quite a bit weaker than you, so it isnt terribly fair sport either. 

If you are level 26+, you should also steer clear if anyone under level 26, as they don't have access to soldiers that can defend against yours, not many men on towers and low level farms incapable of feeding as many soldiers as yours. For these reasons hitting an under 26 level at higher levels is like clubbing baby seals. Not very fair to the seal.
