Is it possible to Deep AoE to 65 with the launch of PoP on Aradune or does the exp stop at 63 64 etc?
I would suggest skipping aoeing the deep at all. Not because the exp isn't good, but because of the easy ban hammer. As for how high you can aoe, Deep west will take you all the way to 70, but the exp drops off to nothing past 67 or 68. Once my guys hit 68, it was more efficient to go group/duo exp in a real zone than toss krono to someone for a plvl. That is based on prior TLPs though.
PoI is actually not better than the deep. Level difference isn't much and pathing is way worse which can make for longer and riskier pulls. For 65-70, paw is best if you don't have an enchanter. Vxed is best if you have an enchanter. In paw you run the risk of competition eating into your pulls -- a good grind group can easily clear almost the entire zone but the pick threshold is 20 or so. Vxed obviously doesn't have that problem.
