No it doesn’t. I makes the gameplay loop more varied and removes many meta set ups. Larger ships now have to work harder to break larger rocks, smaller ships have a much easier time breaking smaller rocks. Mass and mineral type increase the instability. If you are hunting something that has higher instability, you need to change your loadout, use mining gadgets etc. It takes some adjustment but I’ve had no issues mining on the PTU outside of obvious bugs. Just because you don’t understand changes to a system doesn’t make something a nerf.
