I've seen this before, the editing is awesome, same as the stunts. I've only tried a few stunts myself, but this guy is just too good...
My fav. part is 03.24 and the one in the strip club ^^
Edit: Oh and 04:16 is just epic..
this is also pretty funny^ Never got the chance myself to do it since my 360 is dead...sigh
Check out WoW videos by Dance, Grim, Neilyo, Kenion, Tosan, Krymu and Nihilum's Awake.
Some of my faves:
Shadow Word: Dance 3 By Dance
Insanely good editing.
Kenion - Eviscerape 2 By Kenion
Really good music.
World First: Nihilum Vs. Illidan Stormrage By Nihilum
Superb editing with great epic music.
Krymu 5 - Rogue PvP By Krymu
Good music, skill and editing. 60fps video is smooth as hell but can be laggy on older computers.
Neilyo 13 - Random 2v2 By Neilyo
Neilyo has good taste in music.
