imo the GvG system is a bad system. But, there should at least be some visual marker if a group is on the list. VERY often, in a small man we will come across a large fight. We often assist our realm .. Then the friendly realm members will pull off and let my small man die. I understand that they are trying to get a clean fight. If I knew they were a GvG fight I would not add. I would like it a lot if they were confined to an instance arena .. but the next best thing would be to have some kind of visual marker. A large pennant flag, a tall light column, something. It is a socially toxic system currently. It looks a lot like cross-realming to people who do not know about the system.
