Resetting favor was, I feel, a bad move. I feel I am being punished for something that I did not do. The reason that has been given is that because some favor was not reported correctly for some games. From reading posts on these forums, it seems the same thing is happening again after the patch. It also seems that because the cause has not been fixed, the same thing may happen again sometime in the future.
I had spent 4000ish minutes (70ish hours) getting roughly 11k favor. I do not relish the prospect of having to grind out that favor again. I am not a fan of being forced to do something over and over again to get back to where I was to begin with. As an example, in Call of Duty 4, I played online with some friends. There was the option to reset your level from 55 back to 1 in order to get a fancy new icon next to your name. Some of my friends said they enjoyed earning all their achievements over again and releveling. I, however, chose to keep my five little stars because having to earn every weapon all over again was NOT my idea of a good time.
Taking away something someone has earned is, on the whole, something society sees as bad. A better solution would have been to just give everyone some bonus favor to make up for any that had been inappropriately lost. Those people that got a little bonus favor through errors in the system would be ahead, but really this would not have been such a big deal. Those people that intentionally abused the system should be dealt with on an individual basis through warnings or bans.
In the future, I hope this will not happen again, or that it is handled a different way. I'd be in favor of returning all the favor that was taken in this instance as well.
