Cryptic is asking Champions Online players via a poll on the official website. They make it clear that this poll doesn't ensure the winner will see implementation, however. Cryptic is essentially licking their thumb and sticking it in the wind, rather than mapping exactly what the community wants to see -- which is probably the best choice.
Nevertheless, it's undoubtedly a good sign when a developer takes an active interest in what kinds of content its community is most interested in seeing. Plus, it shows us what kind of content we may be seeing in the many months of Champions Online yet to come. So, we hope those of you playing cast your vote, because more than ever before, Cryptic is listening to what you've got to say.
