I'll give my honest opinion, even if it's irrelevant. I'll try to construct it a little.
I was bit disappointed. The editing is pretty good, the content not so much.
All we see is a bunch of big crit numbers. I was expecting a twink vs twink content, maybe with some arenas and duels included, or some nice handling of abilities between gcd and so on. Maybe some close fights as well, even some losses and revenges.
That "2v1" (which technically is a "1v2"), can't really be considered as one, as the priest is just running around like a headless chicken and not using any ability, and the mage is undergeared, mounted and s-keying all the time.
For the transitions try adding something more original instead of just using your class' morphs, some sparkles here and there, or rare items that people would wanna farm.
You can find many old vids where you can dig ideas for your next ones : Brumble, Boostz, Subjection, Garglablamo, Kladshei, Schultz, Powerglove, Kaylol and many other whose names i forgot, from the golden age of Nightfall 39 twinking. Here's one, as an example (doesnt'have to be that long, but Brumble was a legend) :
Your editing is good though, so just a more interesting or challenging content should make your next one way better. Looking forward to it anyways.
