Are there any downsides to lowering the costs of the unused(in ranked) War Elephants, Shotel Warriors, Condottiero, Teutonic Knights, Turtle Ships, Steppe Lancers and Siege Towers?

For Italians, I think Condottiero also need slight buff.
+1 PA and +4vs Eagles will be good. And maybe discount, like -10F.

But im also propose swich gold-food cost balance to like 15F 55G
