The Honeymoon is over, gamers do what they always do, they exploit the rules to it's limits. As intended, 15 LY was meant for players to grab a system, build the economy and move on and make it all self-supporting. What actually happened is players decided to push to places where no economy is needed, creating an expansion with 99% of it being not colonized. Why do you need to bridge Colonia? You can already go there and no economy is needed in between ( Would agree maybe have small systems every 5000LY is reasonable). Why go to the California Nebula? So your colonies can be destroyed by Tharogids over and over? Not that you ever needed them. it makes no sense.
This expansion needs 3 things:
1. A timer of at least one week per claim. NO range cap go where you want but with a warning of Thargoids if you go too far.
2. You have to build up enough to have 2 tier 3 points to spend to claim the new system ( No large orbitals are allowed from your initial build)
3. A guide on how to colonize. Me and another player have figured out most of it out on our own with testing and scouring The Elite Wiki to corelate commodities and economies and how it should scale. We have a good idea what to build and where but this took us nearly 3 weeks but still has gaps.
Unfortunately it is too broken to be fixed now. The greedy rich players ruined it for everyone. You can say "Hey! BETA" But if no rollbacks or resets are occurring, no once cares. The damage cannot be undone.
