Somewhere along the way the Horde/Alliance imbalance became enough that it became its own feedback loop where people would roll/change to horde because there weren’t as many Alliance, which would cause people to change/roll horde because there were less Alliance, etc.
Not sure how to fix it. If the faction imbalance gets bad enough that I see it even on my Alliance-heavy server I guess I’ll just bow out again because I will never, ever roll a Horde toon again.
