1. I love the graphics.
2. I like the crafting system. It actually makes you feel somewhat special when you succeed a tough recipe. I prefer this system a lot more to the WoW/LotrO gather mats, click craft, succeed system.
3. Somewhat related to 1, but after playing WoW and LotrO for a while, its nice to cloth armour look like cloth, leather look like leather and mail look like mail.
4. I like the customization with the classes that we have currently, though I can understand if some of this will get taken away in order to give us more focused roles. I like that you can play every class on one character, which makes you feel like your other efforts(crafting/gathering/storyline) is not wasted on alts.
