Let us compile a list of D3 annoyances.

I don't like the fact that when I use one grade of potion (say greater) and when it's used up, I have to manually put in the lesser healing potions in the potion hotkey slot. IMO pressing Q should use potions in reserve too.

Also, the chat sucks. I press enter and then I have to pick tab to and select who i want to talk to. There needs to be a button to quickly cycle because in the middle of a game I can't quickly select who I want to talk too.

4 player games just feel really small, and hardly anyone joins the public ones.
