Definately being a dick with wobbufett would involve using him in a cheap way that would allow your opponent to defeat your wob only with a 1 or 2 shot kill move.
Not all our gym leaders can pack anti-wobbers, and they shouldn't have to. I personally see why the wobbuwall trategy is kinda fun at first, but in the long run it takes no creativity to set it up. it is simply a formulaic approach where one size fits almost all. That plan didn't even work for ash ketchum, so you shouldn't count on that to work for you.
