Needs a lot of work.
For a company like Amazon, I would think having enough servers would not be an issue. Especially with the promise they showed during the beta.
The queuing system to login to the game is broken. If your 1000+ don't even bother waiting. You will get randomly kicked from the queue anyways.
Gameplay isn't terrible, though it seems to be incredibly repetitive. Storyline quests will eventually throw you into scenarios you aren't high enough in level to handle.
I still think it has the capacity to be a great game, and probably will be with time however currently, it needs a bit of work.
