Do group buffs stack? Guild buffs?

[McWaffle]

do 5 people with purchased group buffs stack? How about guild buffs?

If so does anyone wanna get a 5 man , 5 buff farm team going ?

If the guild buff stacks as well i will buy a guild for group buff purposes.

guild buffs stack duration, I think group buffs stack at least 1x in value. Not sure if having 3 people in a group with them is triple or not, but double worked in beta.

Hmm , well If anyone wants to grab a group buff and see let me know
