There’s no evidence, it’s called “repeating the same stupid thing over and over again” in the hopes that somebody will believe it. Also, Gloria never supports their statements, they just deny the reality of any data they disagree with.
CCP and other devs have literally proven that one huge factor that drives people out of MMOs featuring full PvP is being victimized by player-killers, PKers, griefers, whatever you want to call them. See this post:
While not the only factor in causing fewer players to remain in EVE, wardecs and ganking certainly result in thousands and more likely tens of thousands of players leaving EVE every year.
Gloria does both. Hence why waving their arms so frantically saying “No no the problem is people who talk about ganking, not the actual gankers!”.
Gloria is one of a small percentage of EVE players who literally squat in high sec, the starter point of the game, p1ssing in the well… and then accuse anyone who points that out as “killing EVE”.
Understand, I don’t advocate the complete removal of ganking or of wardecs. EVE is intended to be harsh. But there’s harsh and then there’s just plain stupid. So far CCP is being stupid, and EVE is paying the price. And as the post I linked shows, they even know they’re paying the price and are asking players/the CSM for help in resolving it.
