I actually agree with Jayce and Sombra here. Thats what made Joining K'Hara or the Vag's something worthwhile, as they make you work to get what you want, which is something that I really like. Sombra also made a good point that their not unique once everyone has them, and then there would be no point to join the official faction's of the nomads either. It was always an incentive of joining to get what you want, but also learning how to RP a nomad and many other things over time.
I honestly think Sombra hit the nail on the head rather well with all of his posts
