Yeah, this. Look at those L50 numbers. Siel Asmos have 110+ L50s in the Abyss while Elyos had 20?
I was in the Abyss a little after siege time, questing my 31 Cleric on rubbish mobs in the Roah Ruins, a good distance from the fortress. Group of Asmos that must have been 50s came to my "safe" Elyos camp, killed the guards, killed the tower, and far as I could tell, didn't even get scratched. Then left me alone and flew away which, kudos for having the decency to not kill an obvious lowbie.
