Well, Smogon has completed round one of suspect testing. So far, the super-majorities removed Deoxys-N, -A, Shaymin-S, and the ability Inconsistent. Now, Manaphy, and Drizzle are next for suspects. I don't remember if there are more than those two, but still. I have a feeling Drizzle will be banned this time around, and Manaphy will go with it. There's almost no doubt about it. We were complaining about a +2 boost last gen. Now it's +3? That's nuts. It's ability to really dent, anything now is just, unbelievable. As for other pokemon people want removed. I don't see Wobbuffet as a real problem anymore, as so many pokemon recieved, and use taunt, it'd be hard for Wobbers to really get in. There have also been a couple new Shadow Taggers who sort of make better use of the ability, in a more offensive nature. As for Deoxys-S and Deoxys-D, Mischievous Heart really kills the two of these. Priority taunt makes Deoxys-S's speed worthless for getting SR or Spikes Down, and Deoxys-D isn't fast enough to setup like Deoxys-S, so Taunt will always stop it. Offensively, neither will be doing too much damage, as both have atk/spa stats under base 100, which won't be doing too much without a boost (which would be stopped by taunt).
For anyone complaining about Tyranitar/Doryuuzu/Ulgamoth/Ononokusu, Drop it. They have way too many counters to actually be a huge threat to OU. Tyranitar has always had a lot of counters, and now it has even more with Waruvial, Poison Heal Gliscor, Roobpushin, and specifically Nageki, with its massive defenses. Doryuuzu is stopped by any sort of priority, or other weathers being brought in. Is it powerful? Yes. Is it a massive threat to the entire metagame? Sure. Is it unstoppable in a sense where the metagame revolves around it to stop it? No. Not even close. Ulgamoth is crippled by SR and special walls, such as Blissey or Vuljiina. Most Ulgamoth also run HP rock, so a pokemon like Blissey, Heatran, or Kerudio. If Ulgamoth runs Gale, Heatran is the perfect counter. Ulgamoth is just easily stopped like Doryuuzu. Ononokusu is the Rhypherior of this Gen. It's really better left to choice sets, as it won't ever have the chance to get in without losing a large chunk of HP. It's better left to revenge killing.
