I for one would like to cap up to Reno's, cerb, and surprises. As schooners, cutters, brigs, and light frigates all make excellant privateering/freelancer ships and not dedicated warships unlike conni's and thirds. Or have the Age of Pirates/sid meirs pirates capturing crew percentage system in the game.
As a plus would love to send capped traders to port with there cargo so I don't fill my hold.
With all the buffs ai got now, capping is a challenge.
