Fencer:  I would agree with the black rook achievement issue if it stated so in the achievement, for example, you could easily resolve the discussion by stating "Purchase a Black Brain Rook membership level at full price" and call it good.  But unless it states that I will continue to believe that I and the others that got a deal for their brain rook should still get the achievement points as it simply states:  "Purchase a Black Brain Rook membership level."

Thanks.
