With the way the game is setup now, a level 1 can immediately team with a high lvl. The high lvl guy can slaughter things while the low level pulls and/or loots. This works out to a serious power leveling session. Sinsear was saying he was reading that people are getting from 1-50 in a few hours of grinding this way. From there, you're on the path to collecting Champion points, Skyshards, or doing quest lines, which is where the rest of us are.
