Winning snub pvp is so much more rewarding than any other pvp on Disco. That's because snub pvp relies heavily on skill and there is no denying that it is demanding to learn. That's why it is held in high esteem by those who know how hard it is.
Protecting this sector against easy-kills (like with GB razors, missiles, etc) is important to keep long lasting motivation for those who want to become better and are trying to master snub pvp.
I think it makes sense, actually, as snub pvp is the most interesting and fun aspect in Disco pvp (even though it is too hard for me to do successfully most of the time).
