I got a Disciple of Khaine to rank 8 before the server I was on (Forest of Shadows I think) crashed Friday night and never came back up before the open beta ended. I played a few other classes to 3 or 4. My impressions from about 12h of playing:

- Don't use Octopus. Any time I click either mouse button with Octopus running it snaps the camera into top-down view. After closing Octopus it worked fine.
- Classes seem very generic. Disciple of Khaine and Warrior Priest were exact clones with different ability names. The ranged 15dmg ability, the melee 25dmg 25AP ability, the same 250pt 'heal' pool (one was blood, one was spirit,) the same buff that gives you a 20% 22heal proc, etc.
- Public quests are fun, but I hope they add a bunch of instances eventually. Also being #1 in contribution and rolling a 1 making you last for loot sucks.
- The RvR instances are nice and quick. I played the one where you get points for capturing both nodes then it resets, and the one like AB with three nodes you fight for constantly.
- Crafting is... lame and feels like a late addition. Only three gathering professions and two production ones. Cultivating (plant seeds to grow weeds/fungi,) scavenging (all npcs drop 'broken' gear you can salvage/repair, kinda like disenchanting I guess,) and scavenging/butchering (getting meat from animals and random pick-pocket like items from humanoids,) Apothecary (like an Alchemy,) and Talisman Making (like enchanting/jewelcrafting.) There's no world-node gathering, and no way to craft armor/weapons.
- The interface feels bloated. The on-screen messages are irritating, the chat window feels klunky, every now and then I'd have messages overlap (a lot of stuff by the minimap would overlap, even after I lowered the UI scale.)
- Movement just feels... off. It doesn't feel smooth, but when I think about it and watch it the animations _are_ smooth, so I'm not sure what about it bugs me exactly.
- 'Evade' bugs. I've had a lot of npcs give me an out of range error when I attack with melee, even though they're right next to me beating on me. You just have to run away till they reset and try again. This happened a LOT on one of the public quests in the Dark Elf area, the one where you kill 75 little tree guys, then 8 dryads, then the boss. I did the PQ 4 times and all 4 times the final boss had this bug.
- There's no official forum. No one-spot to go for tech support issues and to read about known issues. I'm not too excited about searching through a dozen different forums to research problems I'm having.

On a scale of 1-10 I'd give it a 7. It's fun and I'll probably play it till Wrath when I'm not raiding, but I haven't seen a single thing that would make me want to switch over from WoW.
