Fastest way to level 80-85?

[tkoreaper]

Been a long time since I've played, but figured I'd try to make the most out of my free 7 days. I have a Warlock that I'd like to level up quickly. I see that there are already a ton of guides for getting from 85 to 90, so I thought I'd ask here if anyone knew of a quick way of getting to 85 from lvl 80. Thanks.

I would say just doing quests and leveling. Takes no time from 80-85.
