Also, with Shift-Click on the hero's avatar, you should give the differences between the classes. I discovered that I do 2 damages with no weapons, with the Monk. In-game infos (like mini tutorial or info-balloons) are so useful and "modern", while separate instructions or random discoveries are not, imho.
EDIT: mmm... no, I'm probably wrong about the Monk. But I can bet I see it doing 2 damages when I clicked on low rank enemies...
