So bassically I got 4 geared shammies and lately I've been interested in pve. So I want to level a pali for tanking. My q is what is the best way to level. I can either RAF, from main account then play him and a new char on main just to get the x3 xp ( would linking too, then having a main boost him from account c? ) or just RAF, thenn Just instance boost with a shammy (but the RAF will not go into affect

I'm guessing just 3 boxing (account a (is already a full account)+ new account linked) 2 new char, then have a shammy boost
in instances to get RAF bonus
