A great spot for this is the South Uruk base on the second map, Fort Morn. I used this spot for 500 Uruk kills last week and noticed that most of my finishers were decapitations (I was looking out for it because I knew that was this week's challenge). Aggro groups of Uruks and one will eventually light the signal to call for back up. Once surrounded, jump over an enemy and use Vault Stun to freeze them, stab them in the back 5 times using Critical Strike 2 to triple the value of your hits, and use the
finisher to kill them. Prioritize shield enemies over berserkers over javelin throwers over plain Uruks, which will let you keep the combo going and spam the
finisher to decapitate. Throw in the occasional bow shot to kill fleeing enemies and a Shadow Strike or two to get enemies who are positioned far away and the kills rack up quickly.
I tried to see if one enemy type was decapitated quicker than others or if my position in relation to the enemy changed my kill animation, but it appeared to be random.

is not a guaranteed decapitation; too often you'll just run through the uruk. He used wraith stun and flurry attack (with wraith finisher unlocked)
repeated which makes the uruk's head explode and is considered a decapitation by the game.
