As much as I enjoy being able to shoot underneath someones legs it gets a bit confusing when I am able to fire an arrow between someones legs, hit and kill the archer behind him, then shoot him in the leg all while the poor sod thought he could keep his mate and himself safe with a cavalry shield.
I agree with a lot of what has been said here, in particular, shield size should be a constant, the size of the shield is perfect in my opinion, with slight increases to the amount of damage the things can take.
My opinion of course, but I thought it odd that I was able to do that.
