I was playing as the Bannor today and I realised how useful the Chain of Command could be, but I thought of a differant promotions mechanic that I would rather have. My thoughts are that units who gain expertice in a certain field (ex. City Garrison) would want to grant their expertise to new units. My thought is that for certain promotions once you reach the third tier with a unit, that unit could "settle" in a city and teach all units built in that city the first tier of that promotion. So if I train a Longbowman up to City Garrison III, I could settle the unit in his city so all supsequent units would recieve City Garrison I. The following promotions are the ones that I thought could work with this mechanic: City Garrison City Raider Flanking Navigation (add Promo Navigation III) Sentry Tactics I had thought about Guerilla and Woodsman, but seeing as Woodsman has been converted to FoL, and both would require an added promotion, I thought that they might not be the best candidates. I would not suggest that this system be implemented for all Civs, I thought it could be added onto an existing civ to give a little more flavour. I was thinking that the Austrin might be good candidates and require an Exploration Guild to settle a unit in a city, but other civs could easily use it. Another idea would be to give it to the Kuriotates to make up for their limited cities for unit production, the idea being let their units start stronger to make up for less of them. I had thought about using this as an Amurite feature using Spell promotions and not require settling an Archmage, and then taking away Govannon's ability to teach other units, but I thought that might be too big of a change. Thoughts? Opinions?
