Oops lol, when I said "carry weight", I didn't mean it literally.
I meant that the fact that it has a special ability(shield that blocks) will warrant an impediment on one of its other assets, but not as heavily impact the damage as it currently is; that's abit overkill. It's currently useless as a weapon, and its current block isn't a good enough percentage to excuse such poor damage.
Especially for the price of it.

Though, since you accidentally brought it up: it would be a decent idea to add the handicap of 'slowing you down' when the shield is enabled; and in that event I could see reason to increase the block percentage; to cope for the increased vulnerability.

Also, when it's a decent weapon, I'm down for the idea of having the shield require a routine repairing, based on how much damage it takes. More damage taken without repair = less block percentage.

Checks and balances :].
