Apologies if it's been mentioned, did a couple searches through the thread and elsewhere on the forums.
Any recommendations for 66-68 aoe grind on a paladin (with some caveats)? Basically I'm powering out my paladin as quickly as possible with a dual-boxed, out-of-group T6 resto druid. I did 60-62 and 63-65 in Hellfire on the Path of Conquest (which was quite amazing given that setup - with the festival buff was pulling in ~2.5% every 4 minutes or so doing all of the main Path area and the elite mob area at the bottom in a sequence of 3 pulls).
I've been in The Heap a little bit and while it seems decent there just aren't a ton of mobs (can do 1/2 of it each pull and after it's cleared I'm stuck waiting on repop). I've heard Death's Door may be decent?
Link to paladin armory (not completely optimal but works well for my setup - very little chance of death and I've found that maximizing spell damage has really increased the speed of the pulls):
