I know. The 1.0 polls are likely a major factor in why A Realm Reborn was a success, they can clearly do polls and do them well. The point is, they haven't been doing them right since. Both of your examples are completely unimportant; A vanity contest and the location for a FanFest... They're for fun, and I'm not saying they shouldn't do stuff like that, but they in no way improve the game or inform the developers what kind of content their player base wants. There is no poll asking what kind of content we want. What Jobs we want. What races. Our opinion on the current paradigm, and so on. There is no poll asking why people are leaving. What would bring them back. What game/s people are leaving for. As a result, the developers don't know what is putting us off, what would bring more players in, what other MMOs to look out for. All they know is what hairstyles "we" want.
The excuse given was that they listen to the forums, but as I said, that's a fairly stupid stance to take. The forums are a tiny fraction of the player base. They're also a mess of conflicting opinions, most of the time. Wading through the forums is not an effective way to gather feedback. To top it all off, they seemingly only listen when they want to. The fact that, despite the numerous threads complaining about Atma and the Zodiak questline, we've got the exact same thing with Anima, is proof enough that they're either not listening to all feedback, or are missing important feedback. Clearly "listening to the forums" isn't working. If you make a poll detailing opinions on the Zodiak questline, you would get a crystal clear picture of what people want, and there would be no real reason for Anima to fall into the same pitfalls. They'd know, without a shadow of a doubt, that the majority didn't like X, but they liked Y, then they could focus on a new quest expanding upon the concepts in Y. Only a poll gives them that information, people shouting on the forum wont.
That's not to say they should do a poll and ignore the forums. They should do both, there is certainly value in listening to the forums, but only listening to the forums? A recipe for disaster, as evident by, well, Heavensward. The loudest kid isn't necessarily the one who knows what's best.
