I'm always a fan of people putting out multiboxing videos showing their progress, and I have some suggestions:

1) If you're going to put audio over your video, then you should probably just leave the game footage audio completely muted because when you un-mute it for the boss fights, the music you're listening to at the time mixes with what you're already playing, and it doesn't sound all that great. However, it sounds like you're working on it based on your prior posts.

2) In my opinion, speeding up the entire video (outside of boss fights) feels... weird. Personally, I just don't gain much from watching any video at 300% of its normal speed, and while I understand that the lower-level dungeons are more spread out and boring, perhaps I would suggest that you maybe pick and choose where you want to show some things at normal speed, and then make cuts and transition over to another section of the video. I guess maybe what it comes down to is... What do you want the audience to see, or gain, or learn from watching your video, if anything at all?

3) Those flashing game clients are a large distraction, and if you can stop that from happening, then I would suggest that you do—either by "fixing" whatever is causing it, or by editing it out after it has been recorded.

Ultimately, the videos are yours and the way you present them is entirely up to you, but I noticed that you have Adobe Creative Cloud running in your system tray, so I know you've got more-than-capable editing software at your disposal. But, of course, keep them coming.
