So first things first: I do NOT know if this has been suggested somewhere, I just thought that this could possibly be helpful for those that buff guild members and sometimes are not online to do it.
So as the topic/poll suggests, this is a guild version of a buff market. It would function pretty much the same way as the regular buff market but it would be subjected to a guild by guild basis (guild members of >insert guild here< can only see the buff package(s))
It would be allowable to have a price set of 0 (for those that do not charge members for their buffs) and possibly other additions?
(I do not know if a Set stam usage per member per 24 hours would work? ie: Member can use 300 Stamina from 1 buffer per 24 hours, member can select which buffs they would want)
