Because Blizzard has done something very genius inventive with the token:
- The players who are annoyed by others having access to what they do through P2W means are naturally the ones who can achieve/earn without P2W.
- Boosters are a subset of the above group, because for someone to boost someone else, the first someone needs to be able to do it himself.
- So why offer those service if there was nothing in it for them. Well there is! Through the token they can play the game without paying real money! All they need to do is simply make enough gold boosting others. Essentially any objection they’d have from other players being able to P2W their way through the game is “bribed” in the form of… playing for free!
- And that’s the circle of the token: Players who cannot for whatever reason earn something through their own (in-game) means pay extra real money to fund the playtime of the boosters. And the boosters are more than happy to do it since they have others pay for their playtime, so they swallow any pride and objection they’d have from achievements.
Which is exactly why Blizzard is also so adamant at having superhard modes that reward time-limited exclusive stuff. If the achievements and mounts remained after a season ended, a lot of players who buy boosting services right now would simply wait to outgear the content and overpower it, which would mean massively reduced boosting services.
