A quick fix for the Spanish, who last I checked had the worst win % of all civs on 1v1 Arabia.

Give them Crossbow (but not Arb). That's it, that's the fix. Their Blacksmith bonus means nothing in Feudal because you aren't spending gold then anyway if you aren't picking up Fletching. This gives them a bit more flexibility, they aren't likely to want to go archers long term without arb but it keeps the opponent guessing at the very least and I can't see that it's especially broken.

What do you think?
