There's no possible way you collect player feedback and design insight.
The fact that you're posting here means that you've waded through hundreds of topics decrying all these "fixes" and nerfs. If you guys are seeing the reactions of the player base as anything other than negative, I can't even begin to formulate a response that I'd think would convey how much you guys ignore player feedback.
I know you have to do your song and dance PR routine, but please don't BS us. You guys DON'T listen to feedback, and all the great insight and criticisms posted here DON'T get passed on to anyone. It's way, way too obvious.
I'm not going to convince you of anything you refuse to take at face value. But the work my department (the community team) does isn't completely negated by your perception of the way we operate.
To even think all the player feedback worth noting is on these forums AND negative is shortsighted in and of itself.
You'd convince me if the changes made were anything approaching reasonable. Or, at the very least, changes people have asked for.
Nobody asked for skills to be nerfed. Bashiok himself said pre-release that feeling overpowered in Diablo was what made it fun. Now? Nothing but nerfed skills. You're nerfing skills in a game without competitive multiplayer. Nobody wants that.
Nobody asked for goblins and treasure chests to be nerfed. Yes, Blizzard wants us to farm elites. But so what? Did we buy this game to be marionettes for Blizzard's dev team? No, we paid $60+ to play a game. If we want to farm chests/goblins/etc. So what?
Nobody asked for vases and things like that to be nerfed. How could you have not seen this coming? You put dozens of breakables in on area right after a checkpoint, then are surprised when people use it to farm gold!? And so what if they did use it to farm gold? So what if people farm anything in this game other than your precious elites (that apparently enough people hate farming)? Why not just get rid of everything in this game that drops loot except elite packs? By nerfing every alternative method, you've succeeded in punishing 100% of the player base in an attempt to target a miniscule population of people farming. Nobody wants this.
Nobody asked for an IAS nerf. This draws a bit from the first point about nerfing skills. IAS isn't a necessary stat. It's very good, but nerfing it because someone in your company thinks it's "zomg most important stat everzz!!11!?" Seriously? After people have spent millions of gold on items to cater to certain builds, you guys go and nerf the skills and stats without any real warning. It'd be a lot better if you guys just gave us a strict outline of how you wanted us to play. That way, we won't waste time and money gearing for a playstyle or build that will be needlessly nerfed. Nobody wants this.
Nobody asked for a game creation limit. I know the explanation is "it's for server stability..." but that's hogwash. Over 6 million people bought this game, and there's only a four player limit in rooms, and you guys can't figure out how to run stable servers without screwing over such a huge portion of the population? So if I wanted to farm the materials for the Staff of Herding, I'll now be looking at countless hours of sitting at the main menu because I warped into the oasis a few too many times? What about Hardcore characters that are basically forced to farm chests and goblins? Nobody wants this.
I really want to go on and get a laundry list of grievances posted, but what's the point? There's apparently some population of gamers asking for all these things, but I'm absolutely flabbergasted trying to figure out just where they're at. Definitely not these forums, and definitely not in-game based on the time I've spent in General chat. Throw me a bone, then. Where are the people who wanted this stuff?
