I am a huge fan of the game and had some ideas for executions that Ubisoft could probably use if they are running short on ideas. anyways, here they are:

Warden execution: The Warden takes his longsword and stabs it through his oponent. After, he slices the enemy in half upward.

Lawbringer execution: The Lawbringer takes his opponent's head and slowly pushes the head through the top spike of the poleaxe.

Conqueror execution: The Conqueror wraps the chain of his Flail around his opponent's neck as the victim is facing the opposite direction. After, the Conqueror places his/her foot on his enemy's back and kicks kicks the opponent's back, removing the head completely off the body.



I hope i helped a tiny bit. If you need any other suggestions, feel free to let me know. Thank you and have a great day.
