I think the Zuma are annoying because there is no clear purpose for them being there unlike on Beluaterra where the point of those groups in general is complete destruction.
I though BM is supposed to be player against player unless you are on Beluaterra. I haven't heard a concrete reason yet, why there is Dwilight has an exception also on a small part of the continent.
They do have a purpose though, and I hear there are even some nobles getting close to really working it out. The problem has always been that the Zuma are meant to be completely alien. Their thought process is nothing even close to human, which does lead to all sorts of issues. Just remember even among human cultures things that seem like a minor transgression to one group is a major affront to honour in another.
