theory - perhaps you could make a separate subforum for debate about the situation? that way, those who want to ignore these complaints can do so. as is, they seem to appear at random in "general discussion," both of the goko subforums, and the isotropic subforum. This is probably annoying for folks who just want a lot of talk about Dominion, and it also probably engenders some of the repetition.
I do enjoy reading the debate, even though I haven't contributed much myself. I don't think it belongs in RSP (which I ignore). It is interesting to see where people fall on this issue.
For the OP, keep in mind that for a lot of us, this is effectively the end of a hobby we've been invested in for a couple years now. I think the decline of good strategy talk in the forum is likely to continue even after some of the acrimonious posts go away, just because a smaller percentage of us will be familiar with the new cards.
