I love this idea. This is exactly the medal I would play for, even now on both w3 & w4 (on the Swedish servers) almost all I play for is KOs. I go around KOing members from the dominating alliance there, all day long. As I see it, one of the main goals of this game is to punish those who have done something wrong to you, or if none has, something they have done wrong to your town. There are other goals too of course, like leveling up, doing quests, fighting for forts, gaining equipment, building, team working and so on. Most of these have their medals right now (exept the equipment one, maybe a medal for owning all sets?), but I miss a KO-medal. I guess the other duelling medals are good enough though.
