I've done Azsuna, Val'sharah, and am now about halfway through Highmountain. I just barely hit 108. I have yet to do any dungeons, I've done every bonus objective, I kill every rare I can find, and I loot every treasure I find. I did have some rested xp and did get the bonus xp items from the class hall missions from time to time. I suspect I'll have to go to Stormheim next to hit 110.
One of my few complaints thus far with beta is Malfurion. His voice .... I thought people were exaggerating when they said he was bad. But my god. He's terrible. His "noooo" when Cenarius fell was hilarious.
After doing three zones, I'm shocked that I haven't really run into many "collect X" quests. Highmountain has a few of them. Highmountain was also the first zone I ran into group quests in.
The Huln Highmountain quest was amusing. Since you see other players, you see not only your Huln Highmountain but also every other player as Huln Highmountain. Talk about immersion breaking.
My only other complaint is the stupid fill the bar quests. Some areas I can fill the bar faster than I finish out the other quests in the area. In other areas, I'm lucky to be 50% done by the time I finish the other quests.
That's excluding my complaints regarding the artifact quests. I died 4 times doing the survival hunter one and the frost DK one. I died twice doing the assassination rogue one. I think I died once on one other one that I forgot. My shaman who was in heroic HFC gear when I copied her over has her heals feel like a pittance. I tried to heal that stupid sea giant in the resto artifact quest and despite spam healing him, I was literally watching his health either not move at all or drop. It wouldn't go back up until the mobs we were fighting were dead. Some artifacts I found just outright boring to acquire. Can't say I care much about the back story of the elemental or resto weapons. Ashbringer felt meh. Thinking about it, I can't think of a single artifact I did whose story I did like. Class halls are also rather meh. Seeing the rogue hall in person didn't change my impression of it being crappy. The shaman class hall is meh. The paladin one is rather dark for being a hall for paladins. The warrior one is too bright. Mage one is rather dark. Only class hall I haven't really seen in person is the priest one which I'm not sure I want to. Given how many issues I've had with many of my other toons, I'm not sure I want to level my priest.
