Ok this is what i do fly out to tourney grab all.
Next i goto the ships in sky horde or alliance depends on toon grab all those.
Third go out to do the three at onslaught harbor, then go back to the citadel jousting one then head toward the vyrkul. On the way you can knock out a cpl same time. Do the flying one where u drop the 4 guys then the one you run up mountain escort and king of mountain.
While your in yamerhien or however the heck u spell it you can do blood of chosen slaves and the tourney scourge one all at same time. Then do drag n drop str8 across u can do not a bug the elite dude always forget name of quest where u get his body parts and writhering mass and tfa.
Once u do that i fly to where u collect the armer helm bones set those three off at once with three chars. The put 4 of my toons above where u blew up the abomination and do that one with one.
Then its a little flight but oh well i fly out to stormpeaks and do blowing the horn snowball the jormunger and the find the guy with the wolf. Then fly back to the tourney and do the jousting ones. Turn everything in on the way thru then head back and pick up heroic daily. Do this it might take an hr n a half but you also make 400g Plus then you can do whatever else you want like run more heroics or go famr herbs skins or mines and sell mats up to u. If i spend 3-4 hrs a day i can make a total of 3-4k gold altogether. So thats 1kg per hr or 200g per toon per hr give or take an gold.
