Ha-ha,Ok I went after the Revenge for about the last 5 hours or so and I sunk her using only my deck(and flak) but this is stock, a friend of mine is borrowing my laptop so I only have stock but will try with GWX once I get it back.
I just disabled his guns and ship, moving in.
Taking out small guns with flak
He starts to sink.
Going going.
He fixed one of the big guns fire it right at me hit the command room but the he sunk.
OK there you go, now for GWX
will keep updated
