Just from the changes mentioned in this thread, it seems to me that Frigates will see a lot more play now. Infantry/Galleons/Frigates is a stack I've used to great effect already (the infantry get much better odds than cannon), and it'll be just as viable under the new patch.
Make Grens/Galleons/Frigates; research Assembly Line; mass upgrade the grens, and attack a short sea trip later. Or just bite the bullet and land before attacking cities.
