I don't really get the thing about Taunt being an issue for Wobbuffet. I mean yeah, it beats it, but it's not like Ice Shard Mamoswine beating Salamence in that it doesn't prevent Wobbuffet from doing its job. As a trapper, only a few things on a team need to be vulnerable to it for it to have an impact. And if it gets a kill and a Taunt user comes in, Wobbuffet can just switch out.
That being said, I used it when I first started with BW and found him tricky to use, mostly because Encore would be a real pain with how it doesn't last as long. I was the most successful when I knew its limits. Sometimes I would overestimate it and it would get beaten up. But it can definitely be useful.
