I agree with the comments about capt skills
The ships have changed substantially and being fofced to pay doubloons to move captains between ships, &/or respec skills for captains due to a system change is not fair on the user. At least consider discounting reskilling/retraining to 1 doubloon for ijn skippers for aweek or so.
Oh to mr "pedantic" how many games it will take me to retrain a 17 and 18 point capt? Figure that out, then consider the time required to do so, factoring in the increased difficulty due to an unskilled commander in higher ranked games, and keep the result to yourself.
