Dunno, makes sense to me. What's the point in adding a bunch of whales if they don't share their SEGs because they kill them on their own? Better add active F2P players that won't have the SED to beat SEGs on their own. He probably deemed a bunch of guys on his friend list not active enough anymore, so he went digging through the event rankings. At least that's what I do when I free up a friend spot, just that I look for whales that can kill me SEGs, rather than F2Ps that share SEGs with me. :P
