Just do it the normal way. I mean you spend more time trying to center him verses blazing him the normal way. I've been in multiple groups who tried the "Atheon Push" method and every time people raged for about 30 min in the hour and at the start of the next hour we're all like -blam!- it lets blaze the bastard and end up mopping him in 5-10min. Stop with "Warlock requests" and waisting peoples time and just fight. I'd rather people die fighting Atheon than people die with the famous excuse "He has to be in this spot in order for this method to work." Like stop with the B.S. and use weapons of light.
