Best thing I decided to do was to just mothball every other team I did,until I get the urge to play that class and concentrate on just 1x5 team to 80,I figure after doing endgame i'll get my appetite back for OL/AZE world game play and need a break from Northrend.
1st team I would always do would be one capable of hitting Heroics,whatever format that is for you.
Just so I could rotate in a fresh character for badges gold and whatnot.
Shaman Pally/DK would be my choice.
Hope that helps.
