Isn't Selbina one of the more populated servers? Since new players are asking around about which server is most populated so they can join it and have people to play with, it stands to say that it could be a reason why you always find low level parties so easily, Mychael. Level sync is more for the benefit of larger level gaps. The forthcoming Rested XP would be what benefits you and your friend with a small level gap as the boost would allow them to catch up. All these methods are there to help bridge gaps between people so everyone has potential people to do things with.
