Guild Perk: Bountiful Bags

Did you see it coming? I hope you did. Bountiful Bags is a guild perk that most "highend" guilds have recently hit. How does this affect you?Now without going into too much detail (as I am not guilded in one that high currently), I spoke with a gent and he mentioned that there is around a 10-15% proc. I imagine you are thinking the same thing that I am here. More ore, more leather, more herbs,
