as Gerard Amatin, i think that, in a sandbox, the players should solve problems, not CCP changes in game mechanisms
Either convince players to stop cherry picking (do a csm campaign, videos on you tube, what you want). Or kill the cherrypickers. etc
I hate cherrypickers but it is like scamming, betraying, being a pirate, etc: it is something that you can see in eve, not in usual mmos, and that is “legal”
