So how does Mentoring work? On PC, and in the past, the higher level could just join a low level game, and own everything and the lower level would get pretty decent exp, while the higher level was getting near nothing, and was a very easy way to power level, or if not that many levels in between certainly bridge the gap, and catch your friends up.
But my google-fu skills are lacking because I can't see anywhere about it? I'm sure the above method would still work, but I thought they had put something in specifically to help "catch your friends up"?
