I agree I don't like the whole TC system but the Naval battles in TRP are great.It's not just carriers on both sides doing everything while the rest of the navy does nothing.Naval mechanics are amazing in TRP, maybe you could take a look at it.
Do submarines even do anything? I played a game as Germany and went Sub heavy and eventually sunk every single British convoy and nothing was happening except the British ran out of Rare metals a few times but then quickly got them back so their ic went back up and that was only when they reached 0 convoys, the British divisions in north africa are still in supply and it seems like building any U Boots is just a massive waste of time
Well I once killed a million US troops in Iceland by destroying their convoys pretty sad actually..... I assume the problem with the british is that their colonies produce their own supplies.
