It is my belief that no keyboard was ever touched in developing the UI. As a result, it is the worst UI that I have ever seen in a MMO. There are lots of stuff I would like to see add/changed with the UI. But let me start with one thing, then we go from there.

Hot Keys. I'm only using 3 out of 7 buttons on my mouse because I can't assign keys. I'm only using 1/3 of the keys on my keyboard for the same reason. when I goto a harvest nod, I wanna be able to click a mouse button and start harvesting. Why do I need to go into the main menu???? Many many actions in game are like that.

Give me my hot keys and I promise I will stop complaning for a month.
