In my experience playing NSV many new and first time players join as shaft miner expecting the typical lava land mining experience, however as you well know our system of mining is vastly different to that of other servers. This unexpected difference can cause players to become overwhelmed and can lead to them quitting if not taught to mine properly. My proposal is to change the job name from Shaft Miner to Asteroid Miner, and to put a small general play time requirement on the Asteroid Miner/Shaft Miner job of say a couple of hours to differentiate the job from typical TG style mining and to prevent first time players joining as miner.
Yours sincerely
