It does not matter how much you do to improve anything or how great that expansion ends up being. Most of your player base left will leave and most will not come back. Resetting power will be the singular most devastating thing you could do in December.

I think that may be the top reason why so many left. I haven't been playing that long, a few years, but I'm not happy that alot that I invested in is useless. So I can imagine how the people who've played longer then I have; who invested into armor and builds must feel.The other thing also is the matterweave. It's not very appealing,at least to me anyway.
