Marquis stated above incredible plays happen from time to time.
The point of that statement is that a knee jerk reaction to getting, say, three footshots to clutch a round "omg hacker" shouldn't be taken seriously. Aimbot is addictive because of the power dynamic- if you have the power to drastically impact the match, you will use it as often as you feel you can without being caught.

In this clip, Masenko is being shot at by the archer the stream is speccing. He knows the archer is there, but watch the aim. He goes from aiming at a player to Assasin's left, to directly at Assasin in one motion, snapping onto him and only missing because Assasin steps to the side as the arrow is released. As an archer player, if I'm in Masenko's place trying to shoot at the archer, but I've been aiming at something else instead, my first instinct is to swing my bow over as quickly as possible. Masenko does this as well, but does it perfectly, so that he needs no correction and can immediately release his shot.

Interesting wiggle on Masenko's part. In about half a second, he makes the decision to target the cav riding close to him, realizes the cav isn't attempting to swing, and aims back into the fight. He makes the decision so quickly, in fact, that his aiming reticule didn't even make it to the cav player before going back to the melee, thus causing the unnatural wiggle. In addition (although this is just a personal quirk I suppose), if I've already committed to aiming a shot, why wouldn't I take it, especially if its a giant horse right in my face, unless I didn't mean to aim at him in the first place?

Masenko aims at chest height directly at a wall in front of him, behind which is Marotski, then snaps slightly left to shoot at Assasin who is further back offscreen closer to his spawn. He's not attempting to look down or twist around in an effort to dodge, but is holding his shot, then snaps over once again to shoot. I find it interesting at the angle he initially aims at. In his position, you'd expect an archer to either A.) already be aiming at Assassin if he knew he was there, or B.) be aiming at the feet of the enemy infantry holding in front of him. Instead, he holds a shot aimed into the wall, conveniently pointed at the player who was closest to him (linearly speaking) before Marotski began to pull back. At 20:39, you can once again see him aiming directly at a wall when there's an archer behind it. He's too far away to step around the corner and shoot, which he opts not to attempt anyway, but simply begins his draw while aiming at an archer that he should know is there, but he should also know he can't hit.

Masenko begins his draw, snaps over to the enemy archer in the stables, but cancels his shot immediately. A couple seconds later, he does the same thing- draws his bow, snaps to the archer in the stables, then cancels his shot to 'head bob' at his teammate. Same exact movement, same angle. Inconclusive imo, but it figures in context.
That's three "lucky/glitchy" occurences in a single set, with another few flicks that are suspect. I've wasted an evening going through and looking at this, and while I could spend the next 3 hours analyzing the rest of the match, I'd rather not. He's cheating.
