Hi
I offer this comment with humility because, as I've said before, I have both respect and gratitude for those who enhance my enjoyment of MTW through creating and making available their mods.
However, I did play a (I suspect early) version of Medmod and one of the things I just could not 'get on with' was the way I couldn't get ships through the Straits of Gibraltar. It really intruded into my enjoyment of the game, I'm afraid. It also massively affected the local balance of power; I think I was playing one of the Iberian factions.
I also wonder if the AI could cope with such a stratagem.
I guess we're talking about a subjective lesser of two evils trade off here.
Just my ha'pence worth.
Regards
Victor
