I believe I know why they increased CRW to 4 - 7 regions matching up … to hide the falling activity levels. I have seen more people leave the game from my faction and region in the past 4 weeks than I saw in the previous 11 months.
While wars had built to greater and greater numbers of fights over those months they have started to fall off the past 3 or 4. By putting more regions together they hope to hide this decrease. It is rather convenient for them that the war records from 3 months or so back and further just can’t be accessed.
Sad that instead of working to increase satisfaction and participation then taking the money that would follow they instead prioritize maximum purchases from their dwindling player base in a short-sighted cash grab. Yes there is light at the end of the tunnel … and it is an oncoming train.
