the basics are mostly diablo like, but:

you could keep the mouse button pressed to continue the same action, if moving you continue to move in the mouse pointer direction, if attacking a monster you continue to attack the same monster (for certain with the default attack, and i think you could spam the same special action too with the right mouse button)

you also have the 0-9 buttons where you could put about anything, for example the whirlwind attack of my warrior, and execute it on press.

It's pretty much like Diablo except you don't need to click repeatedly during attacks.

Click to move and do the default attack, but you can simply use 0-9 to execute other actions, it feel weird to point and press a key instead of clicking (I use 1 and 2 for two different attacks). But once you wrapped your head around it works great.

That all sounds good to me. Thanks everyone! (and to Soldak for evidentially giving us a sane UI :)

I also wanted to share that you can attack by using your numbers as shortcuts, similar to mmos. Which does not require one click.
