They slow you down and only absorb a certain amount of damage, and tie up one hand.
That said, they also use up magicka, which if you arent using other spells it can be worth it, but if you are a mage, its not with the cost. If they didnt cost magicka, they would be a viable choice vs dodging the attacks in the first place. So when your warrior comes across a guy with glowing hands, putting the ward up while you dodge around a corner might be worth it, most other uses are not.
