Faction(?) (Destiny 2)

Help a newbie, please tell me, in the wiki it says:
joining a faction gives NM low recharge have super powers and melee attacks;
joining a faction gives KBV quickly rollback super abilities and grenades;
joining a faction gives MO nothing.

So whether it's today , whether ++ entry into MO or faction is for the most part picture, seriously affecting the course of the game(skills, bonuses, etc.)?
