I always thought that "RU" would wind up being a ban-list from NU, not it's own tier :/ . I'm not so sure it's necessary as an entity utterly separate from NU, what purpose does it really serve? NU is kind of a basin for everything not at least UU to settle into, we really didn't need another tier except maybe to create a stable "NU metagame" (which smogon will never be able to get around to doing).
Yeah, I wish I had a picture of someone using a Gravity Hammer on Halo, and photo-shopped Kyurem into it, because that thing just got BANHAMMERED, and rightfully so. Mew and Victini possibly going BL doesn't surprise me either. I'm suspicious of anything with shadow tag, so the narrow escape for wobbuffett saddens me a little. No opinion on Starraptor, I've only seen one this generation so far. It was BL last gen though, and it's still probably one of the best Normal/Flying types around (unlike the **** that is Unpheasant...)
remember the power creep tell me how thinngs like buterfree or farfeched deal with the kind power being thrown around UU this gen(which is aproximatly as powerful as gen 4 OU)? If a tier doesn't come in between UU and NU then the power creep will hit them hard too.
