I think they should expand on the original capture mechanic. Previously you had to manually reconfigure a relay to capture a base. If you combine that with the majority presence at the base and then perhaps include more points to configure after a base is captured to make it usable otherwise you cannot use any structures in the base you could fix the issue. For example: living quarters (replace paperwork), vehicle maintenance point (restock spare parts), field hospital (sanitize equipment), ammunition supply point (resupply weaponry), fuel supply point (change nozzles). Each part of the base should be unusable until it is reconfigured. This way bigger bases would take a concerted effort to take and you couldn’t just have an AI capture bases while still not allowing spawning on bases under attack.
