The bonus to experience points from heirlooms in WoW is disappearing. Apparently, Blizzard has other plans for this equipment.
Those who want to level up quickly in World of Warcraft should equip their characters with heirlooms. These are not only strong equipment at all levels but also provide XP bonuses of 5%-10% in many cases – depending on the slot occupied. This drastically reduces leveling time. However, this bonus is soon to be a thing of the past.
Where does the info come from? In an interview with streamer MrGM, Morgan Day from Blizzard discussed this. According to him, the XP bonus from heirlooms has been removed. In the future, you will not receive additional experience points while wearing heirlooms when killing monsters or completing quests. This change is likely to come with Patch 9.0, the pre-patch for the next expansion Shadowlands.
What comes instead? How Blizzard plans to replace this bonus experience is still unclear. The developers want to create something that is “useful and unique in a similar way”. However, what exactly that will be has not yet been revealed. It also seemed like Blizzard does not have concrete plans yet and is still testing various ideas.

Initial reactions are negative: The comments from players are mostly negative. Many are already complaining that they have invested several hundred thousand gold pieces into their collection of heirlooms to level up twinks quickly. Now losing the main reason for these items feels bad. Most also lack an idea of how Blizzard plans to meaningfully replace this bonus. Therefore, it might not hurt to make use of all currently active XP bonuses while they last.
However, there is also a group of players who do not see it as dramatically. After all, with Shadowlands, the leveling process will be revised and shortened anyway, so the missing bonus XP may not matter much. Such crazy level records in just under 4 hours will probably no longer be possible.
What do you think about the disappearance of the XP bonus? Is it not such a big deal? Or is it a terrible thing that Blizzard should rethink?
