I'm making this thread to ask the TWC EBII community about everyone's favorite regional (non-core, non-faction) units in the game. After securing your homeland, where do you like to send your armies for some juicy regional auxiliaries? Alternatively, you can talk about which regional units compliment which factions best.
For example, I always like adding far-away Iberian or Gallic swordsmen and shield-cavalry to my Hellenic pike armies, even though it's a long way from home. I'll usually try to Capture Syrakousai to use as a mid-way-point for transporting the troops with my navy. I've even abandoned Hellas entirely before and attempted to migrate Epeiros to the Western Mediterranean... it's much easier said than done.
What do you like to use?
