I could be blind but I cannot seem to figure out how to either resize or change the way that the UI displays health bars.

The way it is set up right now does not facilitate efficient targeting and monitoring for healing purposes.

If this doesn't exist I would ask that it be looked at.

Being able to just make the health bars larger WIHOUT making the rest of the UI larger would be an improvement.

Now in order to preempt the naysayers this is MY opinion and I would LIKE to have this option. If you were rabidly against this idea you could keep your setup as-is and would not adversely affect you in any way.
