I noticed recently that you can mine megacyte containing ores in 0.5 moon mining. I think this could be imbalance issue. Usually you get megacyte just from 0.0 and wormholes and random spawning ore belts.
This sence of EVE justice feeling inside me that I have tells me that high sec moon mining should give same T1 minerals than normal belt mining. In high sec you can get tritanium, pyerite, mexallon and isogen. There could also be high/low/null sec T2 raw moon materials. In null sec you could get all materials naturally. EVE is risk vs reward game and moon mining in null sec is much more dangerous than moon mining in 0.5 sec space.
This is open discussion about possible imbalance issue in moon mining. Is it real or is my sense of EVE justice wrong?
