Instead of drinking rum, fighting and killing enemies like real pirates on a ship, they sip on carton juice and avoid conflict. Might have been from TVtropes. They do get on a ship but that’s about it.
I think Deathwing could work very well with this strat. While the team flies as 4 to destroy the keep/fort/core, DW keeps stalling the highest 2-3 dps enemies with meteorites to stop them from hearthing back. Very disgusting strat but effective. Even if they go out of vision he can land on them and interrupt hearths for a long time.
