well in FPS competitive is defined by tactics and strategy more so than levels and skills so in that sense it's not what skills you have but the weapons you have and how you utilize them on a battlefield. If there is no coordination there is no victory, and while I am sure people will have to earn certifications and rank to gain access to various weapons or kit that should be less of a issue, and organization and tactics will play a much larger role.

mors est merces mea – death is my reward
morte in vitam non habet tenaci - Death has no grip on Life.
