if I want to attack someone should I leave my clan to do it so they don’t get hit with “revenge attacks?” Or do I just teleport and move so they don’t see the rest of my clan?
Well that is a question you should ask your clan. If they don't mind shielding and hiding troops then attacking from where you are is fine. If they don't want to participate in the pvp aspect of the game though, then maybe you need to find a clan which does. Teleporting away from your hive though won't help. The map is deceivingly small so it is easy to find a player or clan within 15 minutes of looking.
