Ideas.1. Buff Spartan hoplites (increase cost/upkeep to match, as they are a whole tech level ahead of standard hoplites but are no better).2. Buff Spartan heroes & increase cost/upkeep to match (To stop them being over-powered) - currently no reason to build them over Royal Spartans.3. Add a higher level archer to all of the Greek factions (to prevent using the same archers the entire game, some progression even if it needs the top level auxiliary building).
