I myself have been having huge problems with Sub SD Garchomp lately. It can honestly be rediculous at times. He can set up and break through your Vaporeon with Ice Beam, and easily dodge my Latias's Draco Meteor for revenge killing it. There is some consolation in the fact the Bronzong/Skarmory hard counter that particular set though. It didn't win the manliest pokemon award for no reason- its very fast, very bulky, and when your attack misses he can plow right through your weakened team. Because of its hard counters to the hax abuse set, and the fact that the normal SD needs Outrage to break through all of its counters I say KEEP IT IN OU!
On the subject of weather, I think GameFreak took it too far. You play one weather team, then the next has at least 3 in common with that one. On top of that, there are clear favorites. If any of you have battled Kevin Garrett's Sun team, which I won't reveal, I believe he has already found the "perfect" combination for Sun abuse. I love some of the rain teams ive seen, because they vary from stall-offense, but Sandstorm is the most annoying thing ever. Its the same Mixtar 98% of the time, CB Tar 1% and Hippowdon the other 1%. I wonder what else well find in a cookie cutter sand team, we'll certainly find the same Excadrill. There is Hail, but NO ONE uses it so I cant discuss it much. I try to play balanced, which holds up fine in most situations, but without Heatran you just get instantly destroyed by a well made Sun Team. Blaziken/Venusaur and occasionally Volcarona are nightmares to face. You really do need weather to beat the first two. Blaziken I truly consider broken at this point. It is disgustingly overpowered, as many have said, here's some reasons why-
Blaziken's FB in the sun makes Draco Meteor users like Latios look like wussies, not even matching the initial power and dropping continually from there. It is also 100% uncounterable. Slowbro gets 2HKoed by it and there is no way to gain an advantage by switching in on it. 130 BP Hi Jump Kick? Hippo gets OHKOed after a Swords Dance. If you rely on priority to "check" it, you're getting something Barbecued first. You have to have full health Slowbro/Hippowdon/Cresselia or Scarf Politoed/Tyranitar/Abomasnow switch in at the same time it does if you want to beat it one on one. Even then, Venusaur/Volcarona will take the oppurtunity for the kill right away if your counter isn't beaten due to Protect. Actually, nevermind the scarfers. Speed boost activates immadiately and dooms them.
Overall I am still very happy with this game, Sun needs work, maybe we need to do something about Blaziken, because he destroys non weather teams completely. The other big two are reasonably counter-able. The metagame is very balanced, you just need to prepare for other dominant strategies with your own, there are still plenty of unknown combinations and sets waiting for the light.
