Can someone explain difference b/w BvC, BvB, BvA? I've looked for guides and such, but I'm having a tough time finding anything that's up to date. I understand: BvC = Barb v. Caster build BvB = Barb v. Barb build BvA = Barb v. All? What's the difference between these builds? How do BvBs wipe the floor so easily with BvCs? Where do BvAs fit in?
