Why didn't you say that from the beginning?
Because the Cat Pack is one item, and doesn't really work as an expansion hint for a variety of reasons. The Dragon Pack and the Steamscale Incinerator works because we have a major lore figure in Wrathion who is not only a plot driver but also happens to be a dragon. He has lore tied to both the Dragon Pack and the Steamscale, and we also have a landmass from old Warcraft lore that just happens to be called the Dragon Isles. Hence why those items are more likely clues for the next expansion instead of the cat pack.My issue lies with your selective acceptance of hints though. You either take everything as a hint, or nothing. You accept the Dragon Pack or the Steamscale Incinerator as a hint, but not the Cat Pack, and things like that.
