Staying Classy Through a Guild Transfer
You know, it kind of sucks that you lose in-progress guild achievements when you move a guild to another realm/faction, but what sucks more is that they don't just reset any in-progress achievement. If you have completed an achievement (or several) that are part of a guild meta-achievement, the entire thing is reset, meaning all of the individual achievements that make up the whole meta.
So, in essence, my guild went from being just a few race-class combinations away from getting Stay Classy (I think it was 5 or 6 race-class combinations) and the subsequent 8th guild bank tab to having nothing done for Stay Classy and a million miles away from the 8th guild tab. Had it only reset the races that were incomplete, we would have only been 3 races away.
