I like the idea of a shield that you can see though (
they are already used today by riot police of course!)
actually what do people think would be net effect of having a see through shield. it want;t block your LOS as regular shield potentially* can, but equally that see through benefit goes both ways you can't disguise what your doing behind that shield either.
*I know you don't hold your shield in front of your eyes, but a larger shield can block off your vision to some bits of the immediate area, an effect that can be taken advantage of if you're not careful.
