Blackout is soon gone. Reducing EVE subsciption numbers are probably reason for this. I have idea how to make high efficiency Rorqual mining harder.
High efficiency mining should always be dangerous high visibility activity and require team work. Rorquals should only be able to get mining bonuses when they are in deployed mode. Deployed mode could activate logoff timer that prevents logging off for certain amount of time. In deployed mode Rorquals would be unable to cloak or move. There could also be 1-3 minute undeployment time for Rorquals.
Comments are welcome for my idea.
