I just had a game, in fact its like the 3rd in the past 7 days, where someone was seriously hacking in the H3 ranked playlist, liky flying around and aim botting. Usually on the other team, this time it happened to be mine. How does 343 and Xbox deal with these and is there any other way to report besides the in game report button? I noticed this dude was also changing his gamertag before and after each game, PC player of course.

Make a clip of the cheater doing weird stuff then go to the support site and submit a ticket. There you can report a cheater as well. In fact that was the only way to report cheaters for a long time until they added the ingame report button
