Mining was actually supposed to have been nerfed quite some time ago. Not because I agree with current trade prices but because the intention was never to utterly WTFpwn non-mining commercial factions. They were initially raised to higher levels to draw interest during the education period and allow a somewhat economically famished mod recover. Then they were supposed to be dropped back down. But I'm not an admin anymore and I guess Cannon doesn't really care.
Though it's worth noting that all of you demanded the trade price reduction back in the day as a means to retard the process of securing capships. Brilliant move that.
Even if mining profits were brought down to be in line with upper end trade it would still be an interesting model due to the ability for persons in snubships to profit as mining escorts generate money in a way that trade escorts do not.
I know that 4.86 trade profits are much better than they are now. Xoria did a bangup job and the new runs are going to be epic.
