Miner job xp gain is broken. The fastest way to grind hunter job is mining endstone, giving about 190xp max each time, and that is with 2xp per block. Farming stone the same way gives about 80 xp each time with 0.6 xp per block. Even diamond ore only gives 15.5 xp each, making it impossible to get over 200xp each in the overworld, as the average Ive gotten from mining is around 100-120 xp each time.
So effectively, mining endstone is the best way to level it, wich is not the way it should be, as the point of miner shouldnt be to just mine a useless block for hours. Now, even with the most optimal way to grind xp, the xp gain is still about 1/5-1/8 of what a decent hunter grinder of wich there are several public ones) gives. So grinding Miner is disproportionaly harder than Hunter. Nerfing Hunter wouldnt help the situation either, as it would make it harder for new players to get money and thus result in the economy being split in even clearer clases with nobody having a chance to catch up to baltop and the rich being made even richer by the deflation, that would result from nerfing hunter. As such I recommend buffing Miner exp (and money) gain to make it actually grindable and not nerfing Hunter, as it would break the economy.
