[Suggestion] Unlearning Starbase Upgrades
I have a suggestion for starbases. I would like it if you could have your starbase "forget" certain upgrades to free up upgrade slots.
Say you have an Argonev on your front lines so you decide to give it all combat oriented upgrades to help defend your territory. Later in the game, you've expanded and your Argonev is now well behind your lines and you don't think it'll see too much heavy fighting anymore. So you have it forget a level of offensive upgrades and use the freed up slot to buy a trade port upgrade.
Forgotten abilities would not return any of the capital you invested in them, merely free up the slot. The new upgrades would cost regular price and would take the regular amount of time to upgrade.
Does that seem like a good idea? It seems to make starbases a little better in large games, since it would allow a fully maxed military upgraded starbase to be repurposed rather than become essentially useless. What do you guys think? Does this seem like a good idea?
