Campfires, campfires, campfires .... Something needs to be done about this because, as shown during the last two RvR, people can't control themselves, even when being asked to stop.
I think the concern over sides will balance itself over time as the game grows. Even myself, after the first RvR found myself wanting to join Eos just so I could have more people to hit with my pretty sword.
With what xolotlx said, this is an overall game issue. I felt a lot of the features were there but no way to orientate the players towards them. Some of us may have been the sharpest tools in the shed but we're bound to get some dull ones. There's a lot of questions on basic things ... there needs to be a better tutorial that orientates past the first few levels.
