100% yes!!! atm you the game rewards you for for just spamming left click like a mad man. If I block someone they shouldn't just be able to keep swinging two handed weapons like they are the hulk. After I block they can swing faster than I can as you need the block animation to reset before you start your attack, I'm pretty sure this might even be a bug as it's not like that in SP
Sure allow 3 or 4 consecutive swings but the infinite stamina that allows you to just keep swinging is horrible and rewards for no skill involved.
