Problem with user channels is Joe Schmuckatelli doesn't generally know about them. Then you always have that one guy who refuses to use them, and started in on how you're bringing him down or something like that. Official ones would probably get a lot more use.
To be honest, with all the astroturfing lately, reading a bunch of threads about the same thing doesn't help a whole lot. Especially when it's almost verbatim to the one before it. If there is a specific post, then you're going to need to point to it.
Most MMOs don't give you anything but cut/paste replies regarding bug reports. I can name two that did otherwise, and they were both Richard Garriott games. They don't leave bug reports open until they resolve the issue. They see bug report, put it on some sticky note somewhere, and then close the ticket. The ticket limbo…
No...they won't. These types of people never stop complaining. Even if they get what they want and can just spam one button and win every single encounter, they'll complain that something else is OP.
