I am currently building an energy weapons/VATS character and I am having some difficulty gathering enough MFC to freely use YCS/186 and Multiplas Rifle weapons. They consume a lot of ammo. That said, and even if I do dislike the Van Graffs a lot, which I do, does it make sense to keep them alive to get more ammo? I mean, I have ED-E and Raul as companions, I might even give Raul some rest to get Cass and complete her quest (then get Raul back), but I do NOT want to kill Cass. Should I skip these quests and try to buy ammo from the Van Graffs (if possible at all), in order to keep buying ammo, or is it possible to buy/make enough MFC later on to keep using the aforementioned weapons without the Van Graffs?
One more detail, a but beside the topic: which armor and guns should I handle Raul? Or is he just a synergy for using my own weapons and will never be effective killing or staying alive?
Thanks in advance!
