There has not been one in the single history of the game that went like so.
"Dear forum member, your suggestion is really something interesting we never thought of. We are going to task the development team on it and see if it's something that is viable"
However EVERY blue post EVER goes like this.
"Dear forum member, your suggestion coincides with something we noticed* that had already been under development. (*Here is where the metrics come in). So and so is unbalanced and agree it needs changing"
Just like most of you don't care what 99% of the other posts have to say neither does anybody including blizzard it's just white noise.
So you can complain all you want, RD is BAD, RD is GOOD. It doesn't matter. There are so many conflicting point of views it would be foolish as a company for blizzard to make any decisions based on the voice of the community because unlike the metrics they are capable of viewing, we simply do not display a singular point of view.
In the end we are really just here on the forum to share our tales, promote the game, trade items and interact with each other. Enjoy it for what it is and you won't be pissed off all the time.
