Does the effect stack?
Group 1 = 1 tailor with “Northern Cloth Scavenging”
Group 2 = 5 tailors with “Northern Cloth Scavenging”
Will group 2 get 5 times more “extra” cloth than group 1?

If so will it have to be looted by each toon? Can one toon with “Northern Cloth Scavenging” loot all the “extra” cloth?

Just wondering because I remember people that wanted 5 tailors / 5 flying carpets on there 5 box team. So I would assume there is some one out there that can give us some feed back on this.
