Finals week for me, so won't really have free time until end of week (thinking friday), but I will say I did get a chance to play, and leveling (at least in gloomingmines deep, the tutorial area) is pretty fast, got to level 10 pretty quickly. Also apparently there are hotspot zones (increased EXP earned), although those aren't available till level 20. It also directs you to various dungeons and areas appropriate to your level. I'm going to go out on a limb and also say the armor quests that are ,from what I could tell, inferior to the new armor drops. The really nice new armor "crude defiant" drops on the uncommon-ish side, so it drops often enough, and supposedly everywhere, but its getting your class armor to drop that's the trick...but at least the quests do also offer something to do instead of just mindlessly bashing random mobs in, and fill in pieces for armor slots you may not have acquired anything worthwhile yet.
Didn't have any problems soloing, not to mention there is now added "help" in the form of mercenaries that you can hire. You can hire a tank or healer NPC, and they do apparently take a percentage of the exp from kills, but manage to make leveling pretty fast, from what I'm told.
