Found leves to be a lot more fun if you do them in a party, my friend and I did 25 straight the other night and felt like only an hour had passed, when in reality it had been about 4 (we also did any fates we came across, and the class quests).

Anyone know if there is any kind of feature to "share" leves btw? Only hindrance we had that we found slightly annoying was that we'd each get a different list of leves each time tried to get more, with only 2-3 matching up at a time.
