Buff changes as suggested will make getting buffs a lot easier thank you for listening.

World Buffs

• Players who have completed the appropriate quests related to looting the Head of Onyxia, Heart of Hakkar, or the quests involving killing Rend Blackhand will now be able to hand in a repeatable quest once a month to re-trigger these world buff effects. These new quests grant no rewards and confer no other benefits other than triggering the world buff event on your realm.
• There is now a 10-second cooldown on obtaining a new Darkmoon Faire buff from Sayge in Season of Discovery (was a 4 hour cooldown).
