I have 5 level 90's of different classes achive...I want to get double agent achive but really don't want to level a horde toon from 1 to 90....if I take one of my level 90 toons whom is exalted in the guild I belong too and pay the faction change to change her from alliance to horde and not join any guild on horde side...then 3 days later faction change her back too Alliance and get back in my guild will she get back her exalted status with said guild?
