I watch the character videos under the “learn” menu frequently. It would really be nice to still be able to watch them whenever I want on YouTube, instead of only being able to watch them in game.
The videos are still slightly out of date with regards to graphics. Once the videos are updated to the latest graphics, then they said they will put them onto Youtube. The reason is that once they upload the videos to Youtube, they have a tendency of sticking around for a long time. So, they would rather have the most up-to-date videos sticking around instead of an older version, according to my understanding.
