I think the discussions about what did or did not get nerfed because of PvP is irrelevant to the topic. You don't have to like PvP to understand that having the existing slash command available is being exploited in PvP and it is taking away from the enjoyment of some, so it absolutely needs to be addressed. Asking to remove PvP is unproductive because it isn't going to happen, nor should it. Just like many other aspects of the game, if you don't enjoy it, don't do it. I personally don't care for PvP at all, never really participate in it and don't intend to. With that said, I most certainly do not want to have an exploit like this available that takes away from the enjoyment of those who like PvP. It's not fair to them.
Let's please try to stick to the topic at hand. Perhaps start another thread if you would like to discuss something other than ideas for replacing the base slash command.
