While I can appreciate your views, Numpy, this isn’t the place to share them. Customer Support doesn’t create policy, we simply enforce it. If you feel Multiboxing, which has been a permitted play-style since World of Warcraft launched, should be prohibited, you’ll want to provide your feedback where our Devs will be able to take it into consideration.
Keep in mind, these are long established policies, where all the various pros and cons to allowing it have been taken into consideration numerous times, it would likely take overwhelming public support for such a policy to change. The General Discussion forum is the best spot to engage in that kind of discussion.
