A simple request, how about simply telling us the reason you made this change and how you see the power being used in the future?
I think a lot of the frustrations that people are feeling are related to a lack of information. Simply posting a generic Vision Statement does not do enough to get your playerbase to understand your thought process on specific changes.
So say it like it is. What happenned? I5 went into test and the Burn tankers were still herding too much for the Dev's liking?
Also what kind of consideration is the dev team giving to the fact that nerfs like this one can essentially render a power very undesirable? What is it you expect players to use this power for exactly? If you don't want them to use it for offensive damage, and you kill the recycle so that it can't effectively be used for status protection, and it causes fear which defeats the purpose of taunting, then what is it you see a Fire tanker using this thing for?
Simple answers would go a long way in not only addressing immediate anxieties, it would also go a long way in regaining some confidence from your player base.
Finally, I don't think it is unfair for your customers to expect a certain amount of stability in their gameplay. While these changes may be for valid reasons, they are so severe (I5 in general) that you alter the gameplay drastically. I think we are justified in expecting a little more meat on the notes we get about changes.
Let's face it, MMO customers and the devs have an ongiong relationship with each other.
Just talk to us... some might say that the forum player-base is only a small percentage of the players, but we are the percentage that cares enough about the game to speak freely about our experiences in the game.
