How important, if at all, do you feel that the "Ranged Weapon Support" tree in the Marksman profession is? How much would not having it at all affect your ability to function in combat?

I've always assumed I should have it... but I've been playing with a character generator, and I've worked out a build I am really interested in taking. My problem is this build doesn't leave any points for RWS, and I'm unsure how large an impact that will make in the end.
