Does a shield really help a lot? Ive found some pretty nice ones but since shields didn't really help me in morrowind or oblivion I figured they wouldnt make a difference in skyrim. Im currently lvl 16 with 3 perks in smithing and 13 perks left. Figured id play around with the other skills to see what I like. Trying to stick to a heavily armored orc berserker or something of that sort.
Shield does help a lot. Just look at the perks:
deflect arrows (archers won't be a problem ever again)
elemental protection (the damage of destruction spells that mages cast at you is cut in half!)
quick reflexes + block runner (block when an enemy is doing a powerattack and time will slow down. With block runner, you will have all the ttime in the world to avoid getting hit),
"shield charge" (sprint with shield rised and knock down everything!)
