It just isn't the same without a talking car.
Joking aside, if you're looking for straight constructive feedback on the video and how you could improve it...
1. I'd recommend disabling your view port when recording non-fight content for video production. Depending on your view port addon you could simply write a macro to toggle it on and off as needed. There is no reason the video without your UI needs to be restricted to the same viewport as your UI.
2. I think you can shorten some of the fade to black, some of them seem longer than others. Some of the fades are more faster transitions while others are much slower and it just seems odd that they vary in length so much. Also a bunch of them are too close together. I'd say the frequency of the fading in and out is a bit too often, particularly when it isn't switching between fight and non-fight mode. Like around the 1:40 - 1:50 timeframe you have it fade between two separate shots of just your group standing at a location, deja vu (even though it is a different location). You could have possably done both text overlays on a single video clip, or spread them further apart so that you aren't seeing the exact same thing twice in a row.
3. Your chat window extends up into the world frame when it probably doesn't have to. If you matched the height of that with your viewport you could more easily block it out without it looking too tacky, if there is anything in it you want to censor (such as real id names). You can black box it out without it looking as bad if it didn't extend that high. This is just a good idea in general when recording actual gameplay, just in case something pops up you don't want shown.
4. You did the opening for Magmaw in black and white. While this is a nice sort of style to use for sort of "flashback" moments, hey we already did this, it stands out like a sore thumb cause it's the only time that style was used. Perhaps more could have used this style as well.
Overall it's a good video. Hope you find some of that feedback helpful in making your next video more epic.
