Suggestion: Buy upgrade cores at stations

I know it's supposed to balance the upgrade system that you can't acquire unlimited of them but by the end game I'm feeling like the 40k scrap is just doing nothing and if I lose one of my ships I can buy a new one but it won't do anything close to the old because of how little upgrade cores I have left... I would like to suggest that it would be possible to buy upgrade cores to at stations but at a more reasonable price like 100 scrap or maybe 150 scrap per core to make it fair and more endgame so that my almost unlimited scrap can be useful again because to be honest after the mobile game was upgraded about a week or so ago when the new races where added the game suddenly became very hard and I can't win normal games and I have problems winning normal games now please consider my suggestion
