I don't know about everyone else, but personally, I have modified subs because i thought they were too weak. I gave them my standard speed boost (age #-1) for all ships and an attack and def boost (i think). Subs are 8/4. and nuke subs are 10/6. the most important change is their hidden nationitly. this makes them a useful peace time raider. Its pretty damn fun in my opinion
