There are TONS of quests. They're much better than previous quests though. There are some really awesome quests and later on you'll get into phase changing where entire towns will look different depending on if you've done a quest or not. There's still a ton of Kill/collection quests but they've added some very unique quests. The Wrathgate is one of my favorites. There's others too but I don't wanna spoil them.
Some of the dungeon bosses are really fun the first time you attempt them without a strategy. I think they'll get dull once the surprises are gone but man a few of those bosses caused us to ROFL. Herald Volazj in Ahn'kahet for example was very interesting.
