Good gosh, the whole "offense" idea is completely irrelevant, there's a whole bunch of stuff in this game people might find offending. "omg pirates, mah ancestors were probably robbed and killed by them, lets remove them from the game, i find it offending" "omg torpedoes, my uncle's submarine was bombed by one, lets remove that too". It's irrelevant in any way. Not a way to put down a good idea.
Anyways, I completely support this idea, make it have 2-3 equippable guns to take down shields.
