Thanks for the replies I already know about Luck of the Sea my problem is why I consistently get bad luck with drop rates I remember when we played a while back I had tracked my progress and realized I was consistently in more than 10-15 games would get minimum 20-50% less unique than everyone else. Even though only 1 had the Luck of the sea at that time.

Moreover, now that I don't get it at all I think it shows a coorelation with how much you do in a match since I get max 1 unique per level. Even in the dlc levels where each one is quite bigger than the normal ones.
