One thing I'd say people will want to start doing is to get in on some of these outstanding xp quests much earlier than before (if they're capable of doing so at least). This thread is still very good for pointing out what those quests are. If I were to draw up a plan now I'd start by picking out the best quest in each level range and running it a good 2 levels earlier than what the guide here says. For most people that will result in getting at least 1 or 2 extra days of hitting that quest again without a penalty. It also opens up the option to run normal on repeats during following days since you'll likely have no penalty for doing so.
The tricky part is grouping the quests geographically. Since we can no longer farm the same quest as many times without hefty penalties there'll be a bit more running. A solid plan could help alleviate that.
