There's no guarantee of the winners idea being implemented anytime soon and it's more harm than good to deal with. We already are undergoing a big change with the clan rework with no date said and people still complained that it wasn't fast enough or that people weren't doing their jobs quickly enough.

As cool as it might sound, I'd rather not put anyone in the position of being nagged and scrutinized over this. From past experience the community tends to be impatient in anything they are directly involved in when it comes to ideas and suggestions. You say with updates that the community would be fine to wait, I'd say no but we're both speculating. Though in the long run prevention is better than cure and there is no guarantee the same people will be devs in 2 years or even consider working on whatever the winning idea is.

All in all, I don't think it's worth it. This very board is here for the same purpose. The only difference is the event hypes people so much that they'll grow impatient and it's not really fair to put any devs on a tight schedule with constant updates with their own ordeals going on.
