This discussion came up here- https://forums.civfanatics.com/threads/skirmisher-units.648649/page-3#post-15523877 We want to discuss what ranged units currently do, and what they should do. Especially frigates. In the current system, I find frigates are extremely strong against cities, at least in human hands. Their promotions aren't well balanced either, with logistics being a clearly best choice for the 4th promotion, and this strength making bombardment a generally poor choice against targeting. Frigates have no strategic resource requirement which contributes to making them a very spam-able unit. Cruisers and battleships require iron The move after attacking trait makes any sort of +1 movement bonus incredibly powerful. This includes the Great Lighthouse, the Grand Canal (obtained by winning the treasure fleet world congress proposal), and imperialism's opening policy. I think the important questions are How strong should ranged naval units be against other ships? How strong should ranged naval units be against cities? How strong should ranged naval units be against land units? What units should require iron?
