As an aside to another poster, I do all new content solo, and slowly when it comes out, usually all of N/H/E so I can see it all, explore it completely, and experience the quest as it was meant to and the differences between difficulties. I've got a good enough memory that after 3 runs quests leave few surprises and unless I think they have potential to be added for their xp/min, I'll probably not go back very often. On my last life I do plan to do every quest on elite as I level up so I can knock out the favor at the same time. You might be interested to know that before TRing came along, I did literally do every quest N/H/E on star at the appropriate levels, including all the raids. I think I had a very few left to do, mostly raids since rare is the group that does those on anything but normal.
