Yeah, the huscarl's shield is probably the best anti-ranged shield in the game. That said, it is severely outclassed in melee by plenty of other offerings (similar to how the heavy round is outclassed by the hand pavise, but once again the heavy round has better ranged protection). Whether or not the ranged protection is worth the trade-offs is up to you, I guess. And whether or not the trade-offs actually make sense is up to whoever the heck is balancing this mod nowadays.
