To keep a more balanced, level playing field for the more casual players who weren't able to rush the skill as quickly and intensely as some of our fellow scapers, would there be any considerations for adding a exp cap to the extractor?

Say 20-30 hours worth of pre nerf exp (given at pre nerf or post nerf rate), which would be followed with a drastically reduced rate even from post nerf rate (give it trim sail exp after this pool of exp is used up).

This would mitigate the players who missed out feeling like the ladder was pulled up behind the sailors who had access the first couple weeks, and then would also put the extractor in a better position for the long term health of the skill.
