running assassination animations in black flag resynced

Why does edward now do this awkward scuttle walk after doing a running assassination even if after pressing the button to do said assassination, i let go of the movement stick?Why would they get rid of one of the best animations in the assassination system? It felt real and brutal of a pirate getting his hands on hidden blades to send the guy in an arc, and once he lands he has to brutally pull the blade back out. You could essentially aura farm by holding the button and he'd stay crouched over the corpse with blades extended. Of all the things ive had fullfilled in this game wishes wise, it just feels like oomph is missing from his movement set and edward just feels....too light. Theres just no weight anymore.
