Yeah I found the best way to lvl is just quest and skip the instances....I know this is not as much fun but once you hit 70 then you are at a point that most instances you need are also needed by at least a few other for either rep or items. At 70 I still probably pug at least 50% of my runs fully and at least 85%partially. I post this not because of your comments Evill I know you seem to be a very helpfull person but to all that read this and may feel the same way. 
To everyone in their mid 60s gl on the grind to 70 and my only advice would be stick to quests you lvl about three times faster then instances and make more money.
