I'm not trying to completely crap on your guide, I just want to say that this is not meant for most people. You need to break it up and put important information in front. Instead of giving concepts, give facts, then the concepts later.
Also, if there were was a time line with time stamps for important sections, that would help.
More effort needs to be put into filtering the unnecessary parts of the video and talking, people who play this game a lot and people who have done their research on the character will be looking for new things instead of simple information.
I just think you need to put in a lot more effort in planning things out before hand. Write out a script with specific information, then record a video, then say something over it. Being concise is key.
