Topic: Recycling
Instead of razing infra the only option would be to recycle it.
You would get some cash and resources when you do that.
It would take some ticks to hold the planet that you receive the cash and resources (like 8 ticks).
Attackers would have to hold the planets to make their raid efficient and retakers would try to take back before buildings are destroyed (if they retake before the 8 ticks, they keep the buildings).
The point is that u often have early raids (even later raids) where even if ppl retake, they lose all their infra even if they retake immediatly. When that happens they lose all the efforts they put in the round and if it's an expo raid that fam is more or less dead for the round. Ppl delete or go inactive for weeks and are not motivated to play another round.
With that new thing attackers would have to develop new way of playing (take less planets but try to keep them) and retakers would be motivated to try to have planet back and would go more active instead of giving up.
