Imperial Roman Navy: 1926-1930 Designs

[The Rock Doctor]

Might be beneficial for the leader to be as fast as the little guys.

In general I like both.  Curious to see what you're doing with all the misc. weight on the leader...

[Jefgte]

Might be beneficial for the leader to be as fast as the little guys...

I agree.
-----------------

I think that "Overall" could be 0.75

=> Increase armament to have good escort ship.
