I know that zos has said they dont plan to change this but it is really breaking pvp. Guilds of 60+ are traveling to evenly fought campaigns that they do not have as either home or guest, they take everything then leave to the next campaign to do the same. Lesser populated campaigns scramble to bring the numbers to answer but just cant fast enough. This totally ruins the experience for both the defenders and makes the allies dependent on these other campaign guilds to get the job done. Something really needs change with this.
