so, since I posted last time, I have continued leveling. now that I have beast tribe dailies unlocked, I can agree that they are a godsend. Also, courier leves are almost always worth the extra effort. its a difference between needing 20 leves per 5 levels and needing like 9 leves per 5 levels.

I have been having luck with using courier leves from 15-45, then moving on to the next one and using a week of beast tribe dailies to get 5 levels in 7 days from 45-50.
