So a topic on the official forums turned up about this subject. After a little conversation people started asking for the article. Problem is, I have no idea how old exactly it is or where to find it. Does anyone still remember anything about it?
To clarify the article was about someone asking if petless Hunters or a spec without a pet was ever happening. The response was Ghostcrawler explaining the differences between Warlock and Hunter pets.
Sorry for the... uninteresting topic but I don't know where else to look for it.
