You’re more than welcome. It was literally the biggest subject on the forum for two years. Attempting to explain it doesn’t come close to experiencing it in real time.
The polarization itself is absurd since everyone has the choice to use a ground mount and not fly when there’s flying. There’s no choice when there’s not.
If not flying was popular, then there would be enough people on the ground for people to not notice there were people flying - oh wait… there are enough people on the ground to not notice people flying because they can’t quest or level from the back of a flying mount.
The only thing that makes a difference when there’s flying is people being able to say no to being camped eternally in PvP.
