Do you think Ubisoft new about Stun-Locking when they created ACB?

Yes, that is my gamertag -__-
I don't think they knew about it, but early on after the game's release, they did allow a way for the Y button to be used in Manhunt to desync and try again. However, this couldn't be added in Alliance as it would deny a player's pursuers the opportunity to kill them if they were stunned and desync'ed with Y.

Stun locking is still possible in ACR actually...all you need is to have a better connection then your pursuer...which is quite sad really...
