Didn't they patch out the piercing dmg? Thought they mentioned that in the stream.
Honestly, I don't think it will be missed too much if you consider a CQC galleon with Mino/Carro + explosive light weapon on one side. Charges in, blasts balloon and ship into wall then impacts it to death if the armor doesn't drop and the light gun doesnt get the kill. It'll be a Minolleon! That or a flame thrower on the side...zomg, heavy carro, impact, flames...if I can stick mines in there somewhere it will be the rage quit ship of my dreams.
