I know 0/46 sounds bad but honestly I have heard far worst even double or triple that and I have seen 1/1. I can only imagine what would happen to the price though of said items if they increased the drop rate, because the demand would go up obviously and supply would probably stay the same initially but would go up eventually but you would definitely see a period of price inflation which if you weren't luckly enough to get the drop might end up paying the same amount anyway depending of how much the price increased.

I went 1/28 and a buddy of mine went 1/86 then again another friend went 1/7 lol so 0/46 isn't outside of the norm. I think the worst case I have ever heard of was like 0/100, even in that case the guy is still trying to get it its just that worth it in the long run. good luck once you get it you'll forget all about the number of times you had to kill KB lol.
