I wanted to ask, is it benefitial to invest any perks in blocking with a two-handed greatsword? The skill seems to go up even without a shield. Other skills for my character are heavy armor, archery, smithing and enchanting.
The only beneficial one, imo, is level 1 of the first perk. Blocking is 20% better. Don't bother with its higher levels as it only has a 5% increase per level.
