Hmm, I have heard quite a few things from the double boosting set, so its nice to know its actually pretty good. I didn't see anything special about it at first, but I guess its the simple things that work the best. The points you brought up, such as immunity to sandstorm and good resistances together with crazy high attack are the main reasons I use him, other than just loving his design in general. I suppose you're right: While his individual sets can only do specific jobs, they do said jobs really damn well. Plus, Intimidate is just a plain good ability for any Pokemon to have and helps any team.
