Trade workshop possible use
The other day I was playing a RM game and made bombard cannons to shoot down turk bombard towers. I realized shortly that turk bombard towers outrange bombard cannons. In this moment I wished I could trade in the bombard cannons for trebs.
What if the Trade Workshop building was included in the game for the purpose of "trading in" siege units. You could garrison trebuchets, rams, bombard cannons, onagers, or scorpions etc, in the trade workshop and it would delete them and give you 80% of their cost back so you could spend those resources on other stuff. The Trade Workshop would only be used to trade in siege units. It would make sense because in real life you would physically take apart what you could and the wood and minerals and such would be used to build something different and new.
If this is too strong, you could make it only work for trebuchets, bombard cannons, and rams.
The building is already in the game editor, just unused. I think this would be a good use for it. Thoughts?
