Can we wait to bring up server traffic for the regular CAP ladder before making CAP Ubers? There's only been one person who I've seen even mention a CAP Uber's ladder before this, so it's not like people are begging for it.
Regarding Mini-tournaments, they were phased out because of a lack of interest, and the scoreboard had to be updated regularly. However if they were scheduled instead of "whenever", there would be a ton more server traffic on those times. There are a bunch of ways these could be implemented.
Finally, regarding the rest of the ideas. There isn't much else to say, they're unnecessary and won't bring in people. (How much trivia does CAP have that's not clique-related?)
