I am going to have to disagree, somewhat, with your timeline for the fall of Aion.
Their was a reason so many people were crying about PVP being too much. Back in the day I started on meslam server Asmodian side. Asmos were outnumbered a lot back in the day and was worse on Meslam. Elyos had whole leveling maps blocked off, for days. I remember not being able to leave red mane cavern, being ganked in the "safe zone" in Alsig village in morheim while selling stuff at the general store, having to have an alliance to go to fire temple. Rangers and assassins could literally stun lock you
