Aren't they totally underpowered? Even for games I play as colonial powers I rarely build many of them. Usually I build a couple provinces up to max and let them build ships, the rest either I leave them empty or get to Shipyard (+1 forcelimit), and even then I wonder if that's a good decision. Probably worthwhile when you get to 150% forcelimits, but I rarely go past 110% or 120%. I haven't played those countries that colonize a lot since 1.4, but is it actually more worthwhile now because you routinely go way above forcelimits since you have fewer coastal provinces?
