If you bought BFA on each, you have a instant lvl 110 already, then either:


A: just level normally and enjoy the content (if you want flying later on, you need to do this, complete the story etc).


B: Buy a levelling boost for gold through the freehold dungeon. You most likly see people advert this in tradechat all the time.
(fastest).
