I've participated in plenty of CG's.Statistics and some data uploaded to some website is a academic discussion. The preference how to deal with ganking is a personal one. You said you were ganked...what?...4 or 5 times in several years? Nice! Seems you don't play your so called MMO game not together with other players that much. Go and participate at some CGs. In open please. And not on console. Then you will know about how many players are ganking. Yes, outside of CGs and some engineer systems gankers or other players in general are seldom. But if you talk here about ED being a MMO then the adequate playstyle were to play there where many other players are.
Many of the CG's are competitive...pick a side and it's weapons-free! That's NOT ganking.
