Mythic has always been pretty good about communication with their players. Recently though, one member of their team has gone above and beyond. Bryant, a Senior testing Lead, has been very active on the WAR forums.
He doesn't give any great details or revelations but does more for the community than other developers. Most of his posts just acknowledge a bug and give some sort of status about it. It may be that they know about it and it's been fixed or that it's been added to their tracking system and they are working on it.
You can offer all the in-game rewards that you want, but giving feedback on bug reports is the best way you can encourage more in the future. Most players will feel very satisfied knowing that they were heard and contributed to improving the game.
I don't know how much time it takes Bryant each day to respond on the forums, but it has been well worth it. So please Mythic, give him a bonus or something as he has been doing an excellent job. Dealing with the community is likely not in his job description, so that is really nice of him ;)
Overall I think this is a good lesson in communication. You don't have to spend all your time on the forums writing novels to the players. Acknowledgments and small status updates work wonders.
