Some of the Uber analyses need to be more concise. For example,
Blissey's Wish set and
Mew's first two sets are ridiculously long. I used to be fairly active in DP Ubers, and was on the old ShoddyBattle Top 50 leaderboard under the name MagicBarrier (I believe I peaked somewhere around 30, though I can't remember :\), so I'd be willing to revamp some of the overly long analyses. I'd start on Mew.
A couple of the UU analyses also need to be trimmed down, but the Pokémon are NU anyway and I barely have any experience in UU.
