What is your suggestion?: Give boosters (drop, pet, gauntlet, clue, etc) more minutes per rank similar to how vote books work scaling with your donator rank.
Is this in OSRS?: No I don't think so
Has this suggestion been accepted already?: No
How would this benefit Alora?: It would give more incentive to get your rank up, and would make boosters make more sense with some raids taking 30mins+. I believe it'd also lead to more people buying boosters since they'd be even more useful even though timers will be longer, more will actually use them.
