<div style='font: 12pt ; text-align: left; '>Another good PR one was when people complain how being dead doesn't credit you for any quest that requires you to kill XXX and Blizzard guys post something that's essentially 'don't suck and die' and next patch made it so you DO get credit for kill, since it's stupid unless encounters are meant to never kill anyone!
I know that testing a game is hard, but despite all that, I think anyone could have told you Mortal Strike was overpowered, a warrior talent that instantly doubles your DPS, and now it's nerfed forcing all 40+ Warrior that had a clue to respec because the double DPS skill you've relied on doesn't work anymore. Then again, Blizzard apparently missed the 1.0 Whirlwind (the one that did double damage compare to the nerfed one that was still the most powerful skill pre expansion) and the scaling Corpse Explosion in Diablo 2 too, so who knows what their testers are doing.
Not listening to the public is a good thing because generally the public is dumb and just want things that make them even more ridiculously overpowered. But in Blizzard's case, not only do they listen to the public but they feel it's necessary to mock the public. While the public is stupid it is a very bad PR to post back to the public telling them they're stupid (and Blizzard has a way of making such posts toward people who actually have a valid point to boot). I mean, if they are frustrated with public they can always just get some fans who will happily do it for free.
I remember in beta when the public was posting one dungeon was impossible, Tigole posted back like 'that's because you guys all suck, we developers did it with both hand behind our back'. Mind you, the developer kind of knows a bit more about the encounter than the average player, until someone from FoH did the dungeon naked or something and one upped the 1337 developers. That was a beta incident so not many know about it but if this repeats on say a raid, that'd be a pretty big PR fiasco.</div>
