What's a polite way to avoid adding Rebellion to a raid group outside of events? Was getting dragon scales with a raid of KGB and at least 3 KGB members in the raid were people who made it known they would leave group if I were to invite them. I also don't like grouping with them outside of events as I do have a history with them so I didn't want to add them to my raid, but I didn't want to seem rude. Are we obligated to add them?
