Please don't take my coming words in any sensitive way. I just want to express my opinion about these changes.
The Nerfing of the mining materials prices is like a lethal stab in the back of the entire discovery economy. While i see the point of @Xoria and other developers but i think that these prices will make many players sell their mining ships, change their role play and no longer use mining in game. The large mining factions in the game will get very negatively affected, and i think that some might take it to the extreme and leave, while some will not take it to extreme and will just ignore mining from now on, which is both cases affecting the server in a very negative way. I hope you will reconsider this changes @Xoria and @"LordVipex" .
