I wouldn't mind if it was easy. After the first time the raids can be done considerably shorter they begin to lose they're flare. When a cheese is found people will flock to it for various reasons. For me it's because I have less time to play games so I cheese so I can do it with my 3 characters. If everyone had ghallahorns it will make it somewhat easier but that is more for the bosses. The ghallahorn will not help greatly with other areas and if you have a good team you can do these bosses in a few minutes so to me it doesn't matter if he sells it
