I love Daliant's videos, with Parkour (linked in OP) and Two Dwarves One Eye being the best. I enjoy his mashup videos as well for the music and fun footage.

I think he used to have a longer Sky Trio video that showed them doing a lot more mobs, which I liked, but it's gone. Would love to see mashup videos like his Veeshan's Peak and two The Mystical Order videos redone for Velious, especially if they showed full clears of NToV instead of just zone pulls.
