True story. What i did with my chars and teams is:
80->82 in Hyjal. Once you did all the quest there you have 1/4 exp of level 83.
Skip Vasj'Jir water zone (i hate it)
82-83.75% Deepholme
83.75%->84 Uldum (quests suck here, just do the easy ones untill you get level 84.
84-85 Go to Highland 84-85 zone as soon as you level up and do all the quests here. Most collection quests here drop for the whole party, and you have a nice deck of level 84 greens/blues once you get 85. I also found an epic robe that sold for 8.5k here last time i leveled my 4 dk's.
