RAF duo almost 60 Hellfire quests or instances?

So I've got my Druid (tanking so far) and Priest (holy) heading into Hellfire tonight.

I've got a well geared Paladin (on a 3rd account) that could probably solo Ramparts through parts of the coilfang instances...

I'm thinking I respec the druid to resto and just have my paladin aoe large groups in ramparts.

Think this would be faster than quests?

My goal is to be as close to 70 before LK (yeah, I know it won't be even close lol)

Thanks in advance!

quests, trying to aoe large groups of mobs will probably get you killed a lot.

The paladin is lvl 70 :) dunno if that was clear.
