The Rogue AA Escape only reduces hate here. On Live, as soon as you hit Escape, you would be removed from combat and put into somewhat of an SoS invis, so nothing could see you. I would sneak and hide asap, so I'm not sure how long that invis last for. It wasn't a buff or anything, it just kind of happened. I'm not sure if this has been brought up, but I didn't see any posts for it.
Thanks,
