What do we actually do with a drunken sailor?

I really want Rare to do something useful with the grog in the game, rather than it just being a fun side thing to do because there's actually some potential for grog being useful in a combat situation. Imagine if the grog gave a % mitigation for every mug you drank, lets say 20% each time up to a cap of 80%, every time you drank one it would be increasingly harder to navigate and fight in a battle but you start to become this grog filled behemoth inaccurately shooting blunderbuss pellets while stumbling all over the place and blinding everyone with vomit. Considering how hard it actually is to fight while drunk I think that would be a good trade off and it would actually make grog an important tool to be used while providing a fun play-style option to players. That and getting your friend drunk while you're being attacked and launching him from a cannon into the enemy ship to fight off 4 people at once in a hilarious fashion just sounds beautiful to me. What do you guys think?
