personally, I think all drops get nerfed a bit at the start of ladder. first month of ladder, tal chest or ammy is tough to get, as soon as it's 1 month into ladder, tal chest and ammy drop like crazy. when it comes to dropping hrs, having at least 3 players in game will make a noticeable impact on your hr drops. I have an 8 player game and I get about 5 hrs per day
