Many have tried this and it never worked. Honestly Blizzard should fix it as it makes no sense to ignore it. Their quality continues to be trash with each patch being buggy messes.
I shouldn’t have to try to use a “trick” to get rep some don’t have to. Fix it or allow gm’s to give 1 point of rep or a quest to kill one raid boss gives 1 point. There is 3 solutions that im sure blizzard will never do because they aren’t a quality company anymore.
