I am just wondering if it there is any work around to being able to queue for instances whilst levelling up as 5 hunters.

I am close to finishing off my 5 moonkins, where i didn't have much problems with instances in full heirlooms, and I am interested in leveling 5 hunters next. The only situation i can see with 5 hunters is the levelling process 15-70, what i mainly do in instances.

Is there any way around this, or is there a viable questing route to take without outleveling zones too quickly forcing you to run zone to zone too much, annoying ground item quests and such?
