All of year 1 I only ran one character; just didn't want to put in the time for all 3. I was convinced to do it by a clanmate and boy, the level jumping you can do is amazing. I would have been in the 580's had I done this sooner.
Also the Corrupted strike mission at 580 you need to do for the Malfeasance questline.. don't try that at 560. Ouch.
