It's for leveling my pally to 95 this season lol. Not sure how much I'll be playing next season, but I've already leveled the chars I wanna level (excluding this pally). If I'm actually leveling another char next season I'll post up another thread though.
West is basically only all stolen players, because the people over there are all located on the eastern hemisphere. US players aren't really on uswest, they're on east. If all the ppl located on the eastern hemisphere were to move to asia, west would be empty and they would all be playing with the same ppl only they won't be lagging anymore.
