Know what I would like to see? A stat that keeps up with how many times you were ambushed when you attack. There is one for how many you use, just think it would be interesting to see.
We don't keep a log of that stat anywhere to my knowledge, so the count would start from 0 if it were implemented. While this would be an interesting stat to see, it doesn't tie into any other systems like achievements so the likelihood of this making it in is low. I'll still put it in the ideas queue though, thanks for the suggestion.
