Leveling up the skill is a bit tedious along with only 3 action points every day. There should be more options like the oral training to get faster experience points in other stuffs, maybe more gears or pay someone to rain their skills.
Yeah, I agree this is an issue at the moment. I'm planning to balance it using both the things you mentioned plus some other changes and features I have in mind. I really want to keep mindless and unavoidable grinding as low as possible in this game
