I clicked and took a look. If you want more hits I have some ideas.
The main problem is that the video is over 34 minutes long yet the title doesn't say anything special. What I mean is, people will look for something specific, like how to get a vista, or what an armor set looks like, or they want to see a review of a dungeon or of a PvP map... something. The familiar "Let's Play ____" videos on youtube are great for 1) people who want to get the feel for a game, but mainly 2) people watch them for walkthrough.
As for 1) only one video needs to be made, especially when it's 34 minutes long, and you have several. As for 2) if you want to attract people watching this for walkthrough purposes, specify in the title what's going on, like "doing hearts in Gendaren Fields (sp?)" or maybe "WvW in the Eternal Battlegrounds". That way, when your average Joe is wondering how WvW works he clicks your video. The title is critical.
