Only thing not having it available in The DF is doing is keeping out cross server team ups.

Which I have no opinion about because the way Diadem is set up anyway guarantees it will be a colossal cluster {Kupo} at some point anyway. Letting other servers in on the trolling and toxicity really wouldn't change much.

And for the record, I called it as soon as Diadem was implemented that MPKers were going to start trolling in Diadem, by week 2 I was already seeing it.
