Hello everyone
I think it would be interesting and fun establish a Captain/Admiral character with special ability only for each ships class, for example DD/CLs Captain 10% more speed, CVs Captain 10% time lesser for set up planes, BBs Captain 10% more accuracy or power strike etc....They could be bought in store both with resources (Oil and steel and 5% bonus) both with gold (10% bonus) and , with gold cost, they could move from ship to ship of same class.
This could help raise crew until they become veterans and/or help to fight more powerful ships too. Thanks for attention and greetings
