I sympathize Nick. While I can use Buffy to play games, I can't get rid of the error message for HoF. I secretly think it's all a hoax. I'm not sure how much help this thread is but

- Gallics fall 1 xp short of G3 until you get vassalage/theocracy/gg. Guerilla is pretty pointless until G3. Going G2 kinda commits our entire army into burning their 2nd promo just to keep consistent occasional 2 movement speed. Hill defense isn't a weakpoint of the rush. Without any promos at all we're still pretty happy if the enemy decides to attack us on a hill as opposed to flatlands, or us attacking them in a city. It's a costly investment for a future that won't happen if we don't take Seville.
- How do we accumulate high promo gallics? We'll take heavy casualties at first, and then we'll have units that are hurt / not good at defending a city, and then finally we'll tell them to attack the next city and of the few G3 gallics we got, roughly half of them will die again. If we had suicide siege we could accumulate some high promo units, but that would be a construction rush.
- The downside with duns is without stone or PRO, it costs 50 hammers + Masonry to set up. We really need all hands on deck to win the first battle, and 50 hammers is 1-2 axes. I'd rather have that city build 3-4 axes than 2 axes with G1. Would rather have 5-6 axes than 4 axes with G1, etc. I would build Gallics with catapults if I got IW in trade.
- Moving double on hills is still a far cry from being a 2 mover.
- Most importantly we can't hit Seville on the first turn, which means we just have to guess how many troops will reinforce.
- It's rare to get any trade value out of IW, and even then it's usually a couple early religious techs or something. HBR is much better tradebait and we can get IW with it, or most of maths, or even use it to broker peace.
- Economic stagnation is a big issue. Construction rushes have had time to build a foundation, get some cottages, trade routes, maybe even a library. HAs spend much less time sitting in enemy territory and conquer cities for lump sums of gold quickly.
I'd use them to follow up an axe choke, as there's no risk in not finding iron, but that doesn't apply here.
