Brad wants to use the bullet-stream to deal with the spiders. Sure, the shotgun is easier to hit but takes a lot more time. You want to burst the skeleton down as fast as possible before it can shield it's face.
Agreed, but that thing is dark enough that I can't pinpoint its weak spot consistently every time. At least with the shotgun spread I'm doing some damage even if I'm not quite on target.
I do a bullet stream in the general area of their weak spot as they're coming/spawning in; they don't hide their face for awhile when they're fully activated. You have to be spot on and have the time to focus on him though.
