Cheers Zenga. I've actually retired this team now. Level 75 is sufficient for me until Cata hits. I should really try and get another team to 75 now.
I still don't have any level 80s though, so I will return back to them to use all of their rested XP soon. How long does it take to get full rested when you log out in an inn? Totally off topic but maybe someone can advise?
