The bugs are a big no no in my opinion. Nothing has really changed for Venomoth, all it needs is Qd, bug buzz, sleep powder and baton pass. It's extremely difficult to stop its own sweep when you consider that it can just sleep anything that can take bug buzz (moltres etc.) and continue with a practically unresisted STAB move. Baton Pass just pushes it over the top if you bring in something like a Moltres of your own.
Durant is too fast and too powerful for RU to handle. I don't really understand why people think it might be okay now, are you forgetting that it goe Superpower? Previous checks and counters such as Steelix, Klinklang, Magneton and Aggron just get obliterated now.
Cresselia probably would not be broken. Escavalier basically walks all over it unless it carries HP fire (which isn't gonna OHKO any time soon) and which then leaves cresselia obviously walled by other Pokemon. Cofagrigus and Spiritomb cheerfully beat it, not to mention other powerhouses such as Absol. RU could really do with a nice defensive pivot that can be slapped onto teams, and it's not unbreakable either. Spiritomb also ignores Dual Screens thanks to Infiltrator.
