If you put your skill points into block, you can get various forms of this ability.
all of which involves action draining my stamina. bI'm not saying block is useless. I'm saying merely holding up your shield has no point in skyrim, but it should.
I've just loaded my old oblivion game where I was playing a character with shield. headed up to a fort and fought some guys to see enemies stagger when i block their attacks. then i can safely land my own attacks without retaliation. shouldnt this be the whole purpose of block? if my only chance of getting few hits without getting hit back is using shield bash something is broken here.
