Guild Wars 2

Alright .. my question is simple. Let´s say, I want to activate multiple buffs for the guild. How many buffs can I activate at most for the guild, is there a limitation?

example .. Just in Politics are 3x buffs for influence .. can I activate all of them right away & include different once, from different categories .. or .. no?

If I remember correctly then you can’t activate the same buff twice (I think the ‘Activate’ button will be greyed out). But you can activate different buffs at once.
