Right, but what I'm questioning isn't how WotC is going to approach the issues raised, but what the fan reaction will be. Going out of their way to ask for advice of this sort kind of puts WotC in the hot-seat, and we gamers are an impatient and fidgety lot (IME). Every week that goes by from here on out more people will get fed up that "these suggestions" (specifically whichever ones they hold closest to their own hearts) are not getting dealt with. This is already happening, but I think that asking in such a direct and specific way may accelerate the process.
If WotC does address a problem, that's good for that specific problem and for those people who actually like the solution. It's potentially worst for people who either don't see it as a problem or have already dealt with it their own way. And if they actually come out and say that X thing was a failed experiment, that just ticks off more people...
I dunno, like I said I hope I'm just being paranoid. I'm not trying to say that there's problems with CharOp having it's agenda and wanting what it wants - as you pointed out that's true of anyone or any group. All I'm saying is that when you put stuff to the public like this, I think there's going to be an expectation by the public (on an individual basis) that you will deal with the issues in a way that is satisfactory to them. And I think that the 4e player base is just too big to effectively do that for everyone.
I'm sure, like most everything, the fan reaction will be mixed. Essentials is a prime example of that. Personally I loved the direction Essentials took. WotC is ALWAYS in the hot seat when they make a choice or a decision or take a suggestion (heck, how often do we question those "Rule of 3" articles which specifically aim to ANSWER questions?). I understand what you're saying and whatever WotC does, it runs the risk of getting whined about (not saying that you are whining) and I think most people going in should realized this.
This isn't as cut-and-dry as WotC saying, "Spend $20 on this book called Martial Power 3" only for you spend it and get builds for the Wizard. I don't think they're misleading anyone by asking for a consensus on some things people feel are unbalanced mechanically.
Yeah, there will be some people who will be displeased with the level of effort they put in to posting and discussing and mailing WotC. I got frustrated with the Executioner play-test because they largely ignored feedback (and then wrote an article about why they ignored it). But I'm not gonna wage war over it. There's still so much more in D&D and specifically 4th edition that I think it'll take a while for stuff to really hit the fan so to speak.
Though I admit, where you fear you maybe being paranoid, maybe I'm just being overly optimistic. But if nothing comes from this but "we changed the wording of some feats here and there" well at least they opened communication. That's a start, right?
