Balance is changing from update to update, some classes are getting boosts, some are getting nerfs, some suddenly become good in CP. If your party suddenly doesnt need summoner in party composition, you have same services as any other player, class change it. I dont know why you should be getting anything free to be honest.
PS: By no means this is "sudden" change from what i found on search, people were complaining about this quite for some time already how these summons and cubics are ruining pvp balance and that there is quite big chance that they will do something about it when 2.0 is released. Lack of knowledge/information is by no means server problem.
