Sounds like you’re getting the shaft, and up until now have been OK with it. So fix it and ask your friends to split the extra ore they mine due to the boost % diff? Or pay you your fair share. There’s a million ways to address this between you and your friends without complaining about your existing bad deal on the forums.
I mean, I can complain to the devs that I’m not getting a gazillion ISK/hr for [insert justification], but at the end of the day I have to deal with the reality of what the game is.
