Yup. I can tell you I won't be spending anymore money on this game as long as my progress can all be taken away in less than a weeks time. (I spent around $100-150)
I understand it's the game and my fault/should have protected it blah blah blah, but as far as game longevity goes, this war did more harm to the playerbase as a whole than it did to GPA.
GPA to me was always the place for people to learn, and then either teach the next group of new players and hang out, or leave to join a less neutral alliance. It was a good transition point to get people interested in the game in a "safe" setting.
Now that's pretty much gone, and I'm sure the game will keep chugging along, but as long as this style of warfare exists the playerbase will get lower and lower until it dies.
