It is always something we look at, whether it is the case or not. Population is something we watch very carefully. I don't know about calling anyone delusional (which was a tad rude), but I can say that it may not be quite as extreme as some people say. That doesn't mean, however, it goes unnoticed.
He, just like everyone else, has their opinion. I've personally felt that Molten over-extended on how many expansions the server had, which makes it much more difficult to keep up with an acceptable development rate. Warmane, as Molten's successor, and the bulk of us being a part of Molten's old staff, we didn't want to abandon any expansion completely so long as there were people that played on it. Now it falls on us to make hard choices, which eventually is going to make some people feel "abandoned" like they do now. I can't argue that how they feel is wrong, because it's quite understandable how people feel this way.
(Though I must say that the staff prefers to appear as a single entity, and that our opinion is one and united, even when it is not. For the sake of the community.)
Regardless, it doesn't change that we do have plans for MoP development on the long term, and that there's a lot of things we want to do for you guys. As much as some people hate it, Lordaeron is key to our success and growth right now. Once Lordaeron gets a lot of work done on it, we can better shift our development teams towards Cata & MoP and give you guys all what you deserve - which you really do, for your patience.
Many of the staff members understand your frustration, though there's not a whole lot we can do about it at exactly this moment, but we are trying to deliver a bit of what we can. Just the same, though, it can get quite frustrating for us for people to constantly complain, berate and insult us. Especially since it's going to happen one way or another, from one part of the community or another. We had to choose an expansion to pour our focus in, and the others were bound to feel this way.
That all said, we appreciate the patience of those who maintain it, and we appreciate the people who complain; because, really, it's just because they care about their realm and the server and want it to improve just like we do. We would appreciate it also if everyone could keep things civil, also. It would make the staff's lives easier for sure, and getting out of hand wouldn't do much to service any community member either.
