I think it's directed at the old members. Maybe not maliciously (but I don't really know how you could see it any other way.)
I have a Sept 09 join date, and I tend to post exactly the same way some of you are saying you got in trouble for. "This is a straw man" or "If you were that great, you'd finish Shroud phase2 with the other 3-4 competent players.". No warnings, no infractions.
I'm not trying to be mean, that's just how it is. I'm new to DDO, but I'm not new to theorycrafting, character building, planning encounters, MMOs, D&D, or life, and I call it like I see it.
(Of course, now that I say this and "they" read these boards, I'm going to get 2 pages of infractions from month old posts.
