Honestly, I really like Yukon and would hate to see it go. Keeping it in the rtv list sounds good, but it'd probably rarely get played, which is most unfortunate.
Viaduct is my favorite koth map by far, but recently I've begun to dislike it because I get a huge fps drop around the point area. My computer can easily handle tf2, and no matter how low I set the graphics the fps still drops to 20-30 in that area for some reason. It makes scouting and sniping incredibly difficult. Still, I'd rather have it in the rotation than any other koth map.
Although I personally don't like waste from past experiences with it in competitive play, it's actually a pretty decent map. But I wouldn't mind keeping it in the rtv only list as well. After all, I'd rather play on another map with a team then play on waste virtually alone against 5 people.
Other than that, I agree with Paranoid's rotation.
