Dreadnought and the submarines added

Fleet command team has introduced few new ships to keep the players interested a bit longer. One of the biggest drawbacks of the Fleet command game is that after you unlocked all the ships and completes your fleet there isn't much more to do other than playing skirmishes. The player interaction is very limited compared to other games so adding this new ships is a good way to keep the players who have being playing for a while interested. Drawback is that after acquiring few Dreadnoughts that player becomes almost unbeatable. What I like to see it a bit more player interaction in the game , what do you think ?
