If my theory is correct, though (and it's just a non-scientific theory, not a firm position that I'm prepared to defend to the death) then people will probably be better off talking about what they would like to achieve, rather than how much they dislike the mechanics they feel are getting in the way.
Heck, even if I'm completely wrong, it would probably be a useful exercise to frame things in terms of positive effects of getting what you want, rather than negative effects of getting what you don't want.
Yes. Even if your theory is incorrect, discussion of what you want to achieve, and what you need to do it, is generally going to be more constructive than endlessly complaining about what about a game you don't like.
Especially when that game isn't even published yet! Sure, that will be remedied in just a few days, but the point stands, regardless.
There are some fundamental problems with adopting the "always negative" position. Most importantly, it engages the ego - having put a stake in the ground that, "Game X sucks!" one has a problem in removing that stake. Doing so admits to being wrong, and few people are happy to admit that. So, rather than be willing to just pull it out, we tend to beat it in. It goes from, "I don't like it" to "I think it is Objectively Bad" to "It offers
*NO* support for my playstyle", to "WotC is evil and doesn't care about anyone!!!1!" - driving to more and more absolutely negative positions.
As opposed to, "I find this bit problematic, how can I work with it?" It isn't an assertion so much as a question. It is engaging in creative discussion with your fellow gamers, rather than opposing them. And, perhaps most importantly, done well it keeps your mind open, rather than closing, then locking, then barring, then bricking up the door.
There comes a point where it is time to stop complaining about games you don't like, and either engaging in creative discussions about them, or going and talking about things you *do* like, without reference to things you don't.
