My main account has 4 other accounts linked via RAF. Currently I'm leveling 5 characters 1-60 by questing with the RAF XP bonus. All 5 are level 24 as of this evening.

Would it be faster, slower or not noticeably different to boost the 4 chars via instancing with my 80 main? Because of the difference in level, I don't believe I'd receive any XP bonus.

Just wondering what your thoughts are, I'd rather run instances if it won't set me back much....
