To be honest I like balance of both strength and block rate. The reason is that more I block and i got the strength I can take damage better in my opinion. I love have balance of both I used love Block strength but i realize I am not blocking as much. i haven't use any shield that more Shield Strength with my ability called Bulwark that i have 90% block rate.

I have question does the shield's Block Strength does it effect Shield Lob? If anyone knows that will be great.
