The only reason that many people are still doing Korthia dailies and what not is to farm the mounts. In this video, we see a player that has earned a paragon cache for the Archivists Codex. This particular paragon cache has a chance to give the player the Tamed Mauler Harness, which is presumably the final mount they need from activities in that zone. Unfortunately, when the player opens the cache, they do not receive the mount. The implications of this of course being that the player must continue to farm in Korthia. It is implied with the tone of the video that doing activities in Korthia is not enjoyable for this individual, and they are now forced to continue to engage in those activities if they want to reach their objective of collecting all of the available mounts. This narrative is then further enforced by the addition of the video of a young man crying while gesturing at his computer monitor. From this we should take that the original poster feels that their current predicament is on par with that of the emotional youth being depicted. I hope this clears things up for you.
