/facepalm . . . thats a wind up ability, you see the animation? Have you played D3 before? There are no 'melee' abilities like WoW. Some abilities lock on, and others dont. Its a fact.
Are you going to tell us how Athene beat hardcore inferno naked, or are you going to keep pulling BS out of your ass? Clearly all melee abilities hit him, so how the hell was he able to get out of act one?
Keep up little guy. You can do it. Here is the quote from the guy who made the video you posted above: ".... it seems like it depends on the type of monsters. I got hit by zombie and skeleton way out of range, but I can actually dodge most of the attacks from Grotesque.... " Since its clear you have never played D3, Ill let you in on a little secret, Grotesque have 0 ranged abilities. Unless you count PBAoE kamakazi, which can be dodged too.
So yeah. Keep trying.
