For some unknown reason they are not broken for everyone. Don't believe me, don't believe them. Just try it out for yourself and avoid jumping the common panic waggon. If all these reports are true, than there's a high probability that you will also be affected. But the truth is what you see with your own eyes and can't just be "up-voted". I for one know
for sure (assuming nothing will change in the near future) that core mining VOs will still work for me and where I'll pick up the game again - once I can shake off my current addiction to BG3. But even if it would work for you, it certainly can't compete with current Painite mining if you compare cr/hour. If that alone means broken to you, then yeah, it definitely is broken then. Personally, I couldn't care less as four times higher payouts can never compensate for this insane boredom that laser mining means to me.
Good luck!
P.S. VO core mining requires a little more than just blindly shooting prospector limpets at orange glowing asteroids. If that's what you think, I hate to be the one telling you: Git gud. There's a lot to learn for you...
My latest theory is that the current state of the PWA is the first time, were swarm intelligence terribly fails and creative soloists who dare to trust their very own ideas, get a realistic chance to compete with the masses.
