Does anybody know which perks are useful when blocking with a weapon and which require a shield? It has been discussed but I have yet to see any real confirmation. I was curious as to whether anybody has a real answer.

I've only read about quick reflexes and the bashing perks. Confirmation plses

There are many. Elemental protection is one of the best though.

Huh? What do you mean? I believe op was talking about which block perks work when blocking with just a weapon.

The one that slows down time when you block during an enemy power attack.
