Well, the discussion has died down quite a bit, and while we've determined the tiers of a few pokemon, there hasn't been a real conclusion on some of them. Back to the list...
UU's to be tested.
-Walrein
-Glaceon
-Pinsir
-Cacturne
-Lapras
-Ninetales
-Poliwrath
-Hitmonlee
-Leafeon
-Clefable
From my experience, the two of those that really deserve BL are Hitmonlee and Clefable. Hitmonlee plain just hits too hard with Close Combat and has enough coverage that nothing in UU can really take it's hits. Clefable isn't as outright powerful as Hitmonlee but has a huge amount of options, and the more defensive sets are very difficult to stop without a Fighting type (in UU, all of whom are pretty frail with the exception of Top and Poliwrath, should he remain UU). I'm still of the opinion that the rest of them deserve further testing, though BL does seem likely for some (mainly Pinsir, Wrath, and Glaceon).
