A tiny change to DS to benefit those that DON'T run DS.
Change DS so that it no longer creates an obsession. At the moment if no one runs DS (or a perk that will create an obsession) the entire team is penalized for that.
Yes, this could be considered a buff to DS but it's annoying to be punished for not using a meta perk. No obsession actually encourages tunneling... which shouldn't be a thing!
