This is a great change! In that other game most of the commodities came from mission runners recycling loot, the importance of miners there, was a second thought and was the worst profession for isk/hr. This change gives depth and meaning for an industrialist as most of his building has come from someone mining it first.
In regards to Titan ore being the one giving the epitron , I guess this could only mean there was too much titan ore on the fields, will be mined more and probably 'force' beta players to buy and create a market. Maybe not because they can't mine it but, if it's cheaper I don't think they will bother being self sufficient.
