Concerning career mode,
We are definitely looking into making ship-based and advancement-based careers an option, that way, if you want to start with a corvette and work your way up to a destroyer, than you can, or a destroyer to a BB, or a cruiser to a BB, so on.
or if you just want to start with the battleships we will have that option too.
we already have the Nelson in-game, and its a real heavy-hitter
but so far, a lot of the members are students, we don't have a whole lot of time to begin with, but we are working as much as we can
