So we tested the mayhem a mercury can cause to a Galleon. 2 Shots completely cripple all your heavy guns and one more will destroy your engines, you don't even have to aim well for them anymore, just shoot through the ship and you got the Heavy already.
Say bye bye to Galleons if penetration gets implemented.
I make a plea to think of the people that play on the enemy ships as well and not just the guy that shoots the gun. Think of how awful that would be for a spire, a loch shot will take its main gun and hull armor down in just one shot. This is just sad. It's even sadder to think that this penetration feature was 'intended'
