The instances on maps seems like the logical solution without dismantling two entire systems before a large expansion ships.

Also, I feel like something is being overlooked here; the overpopulation thing is a temporary issue, this happened at the beginning of Shadowbringers and we weathered it on Gilgamesh just fine, we made use of the instances on the new maps and did our train runs.

It feels like the thread is asking for a permanent solution to a temporary problem.
