Here's the problem. All the moderately intelligent players know that Wobbs is Uber material and doesn't belong in the OU metagame. So instead of using him, none of us put him on our teams. Since he's not on all the teams, a particular idiot who runs a particular program we use to battle refuses to ban him back to Ubers. The "data" supports this singular person's decision to unban him to satisfy his own bloated ego.
So we either ALL do this nonsense to each other for a couple of months and have no fun playing Pokemon or we accept the fact that until a *ahem* competitor arises for this particular program, we're all doomed to suffer through retarded matches against the broken blue blob.
What right do you have to complain? I don't see you making a battling engine. That "idiot" is also the one who took his free time to make the program that you use all the time to battle, and that "idiot" is the one who still takes his time to keep it up to date.
If you want to badmouth that "idiot" because he made a decision (which was made by him and a lot of other people), then just find a new program to battle on, seriously. Just because we're on the internet, it doesn't mean you have the right to be such an asshole to people who are taking actual time out of their lives to allow you to play this game.
There hasn't been any evidence of Wobbuffet being broken, and it's very hard to find any evidence if you refuse to use the thing because you still think it's uber. If you want evidence, use the goddamn thing and make your own evidence.
We know it hasn't been on "all" teams. The problem is that it's on near-BL usage, and generally, if people aren't using something so much, that it reaches that point, then there's obviously very little evidence that it could be broken.
Anyways, my way to beat Wobbuffet is, like other people have said, is to not try to counter Wobbuffet, but just be able to have a good chance against the rest of the opponent's team. Wobbuffet has never once given me trouble, and in fact, it usually gets its ass kicked pretty badly.
Tickle sounds pretty cool on Wobba, and it's actually not a bad idea to use Pursuit with it. It seems like it might be a better idea to do this with a Dugtrio at hand instead of Tyranitar so that the opponent is truly screwed against Pursuit, but that's just me. I got Tickle to be edited into the analysis a few months ago, but I didn't think anyone'd actually find any use for it. :P
