Would you realistically have those uniforms on board?Switch uniforms! If you're flying a false French flag, it's going to be a dead giveaway if your crew are all wearing British uniforms. OK, not in the game, which doesn't take account of outfits. But when Hornblower was trying to pass himself off as French after sailing into the Spanish fleet in the fog, he had all the crew in French uniforms. As far as I'm concerned, switching uniform when you switch flag isn't a bug, it's an authentic feature.
I seem to remember from the Hornblower books that when flying a false flag, the soldiers had to hide out of sight. The sailors didn't wear uniforms.
Of course in PotC we show only soldiers, which is technically a pretty major oversight.
There is certainly merit to that idea.You first need to purchace the uniform from the tailor before you an use it? And if you don't have it the chance your false flag is deteced will be higher .
