I used the "power leveling" gree thing to get 2 characters to 50, I had a lvl 50 sage healer and a 50 trooper tank pre power lvl, I wanted to go to the imp side, but i loved sage healing and trooper tanking. So I made a bounty hunter tank and a sorcerer healer to match my republic toons. I didn't wanna take the months it would have taken normally to get them to 50, so i power leveled them to continue playing with what I technically already had, since there is no faction change yet. I do not feel bad for doing this at all.
