@smugumin @LukeAlmighty Yeah I believe when the developer created skills he never expected people to reach 99, which is why most of them capped out at functionality at like 70. That didn't stop people from spending massive amounts of time trying to grind it though, which is why they added skill capes as a reward.
I wasted way too much time mining to earn meager gp, but it did teach me a lot of economic concepts as well as to watch out for scammers.
