Some classes are indeed still terrible and screaming bot all around (hunter is one of them). Just don't bot an account you could not accept to lose.
I can see that the ban are still going on Outland (they announce it publicly when somebody gets banned, including the reason why he did, and tonight i saw a couple of "bot banning").
I could not make this to work either.
I used a pretty lame workaround: i placed the spell Mangle (Cat) into the 1st position of the 3rd actionbar and then i was able to call RunMacroText("/click MultiBarRightButton1") from the custom class as lua code.
