Yes please, I have made a lot of uber comps recently sbecause I like them and miss playing Baton Pass, but I can't find any use to them aside from the battle tower, its really hard to find any uber PvP matches atm, even in vermilion. Sometimes people battle me with a team of OUs and that makes me feel dirty..
About legendary dogs/birds, they most likely won't ever become uber. On smogon gen5, moltres/entei are RU, zapdos/suicune/raikou are UU, and articuno is NU. What we really need to make ubers a thing are legendaries like mewtwo/rayquaza/groudon/kyogre/lugia/ho-oh/arceus/giratina, but we probably won't ever get these cause staff thinks they should be unique, which I kinda agree, some exceptions could be made since it was shown on the anime that there is more than 1 lugia in existence, but it'd be unfair if not everyone was able to get it
