Pretty late in a game right now, and I support putting Cruisers to 1 range. But, I do think Coal needs to be visited as a Strategic Resource. A major issue is how hard it is to build melee naval units compared to ranged, which completely throws off naval balance. Cruisers (and later ranged units) are allowed to dominate because they only take Iron, which is a useless resource at that stage anyway, while Coal is extremely limited and necessary for three extremely strong buildings. I almost never have Coal for units unless I'm playing a warmongering game, and even that can be hard.
