Blackout is soon gone. Reducing EVE subsciption numbers are probably reason for this. I have idea how to lower plex price and make EVE more interesting place after blackout.
Plex price has increased because endless amount of multiaccount Rorqual miners are maintaining their accounts with plex. I propose fix for this. You can only pay 1-2 subsciption accounts with plex and rest needs to be payed other ways with real money. This would lower plex price and attract more subscibers for EVE.
You can add 1 more status. For example, gold omega. a character with this status only can buy PLEX. Only when a character is brought into the game with this status can windows with usually omega status be started. Gold omega status can be acquired only for payment in your account on the EVE website.
