Due to the very tough level phase in Classic, a lot of players resort to the option of getting boosted. The chat is hardly readable anymore, because 9 out of 10 messages consist of level boosts. Blizzard is now reacting and will soon make some adjustments to group XP and NPC mechanics.
One of the most common pieces of feedback we’ve received (and observed ourselves in our own adventures) is the concern about pervasive sales of dungeon boosting services in-game. It often overpowers chat with advertisements and makes certain channels hard to use for their intended purpose.Community Manager Kaivax
It’s also no secret that the gold from many boosting groups is used for illicit activities such as Real-Money Trading (RMT), as much of the gold that players pay to boosters is then sold for real money back to other players.
Now that we’ve seen the final major content release of Burning Crusade Classic, we will soon adjust the behavior of creatures in most dungeons (including the new dungeons coming in Wrath of the Lich King Classic) to make it significantly more difficult to endlessly snare and kite enemies. Additionally, we will implement a reduction to group XP earned when there is large disparity between player levels in the same group.
We’ve experimented with similar changes to most dungeons on our Season of Mastery servers, and we’ve found these changes to be very effective at reducing the efficiency of boosting groups. We plan to roll out these adjustments to Burning Crusade Classic realms at the same time as the global XP Buff (Post) which should happen sometime in the next several weeks.
