That video proves nothing. If you get hit and don't move, that is your blink. Once you swing or move, your blink runs out and you immediately take damage. None of those examples are "lag blocking". Even in the last example, Male probably was hit into the door and the arrows that come from the side don't hurt him because... *drum roll* ...they don't touch him!

My goodness, you reek of denial. Is it too much to ask of you to swallow your pride, even for a brief moment?
