I love that when you mouse-over an opponent on screen you can see their health bar. However, the mouseover health bars are often really inaccurate, usually showing that the opponent has a much lower percentage of health than they actually do. For example, it will often show like 1/4 of a bar when the character is actually at like 50% health. (I'm talking about the little healthbar with no text that appears over their head in the main window, not the more detailed healthbar you see in the info pane when you target someone.)

I think this problem might have something to do with the camera zoom, because the degree of inaccuracy seems to change depending on how far I zoom out. If I zoom in and out while hovering the mouse over a wounded opponent, I can actually see the healthbar changing.
