yeah you are always on the right, visually, no matter the player, but I understand your frustration. The weapon rolling is why I left a negative review the first day I played, it is without excuse that players are allowed to fight their hearts out for 30+ minute games sometimes to get a weapon drop and then potentially get NOTHING for that time.
What platform are you on? If on PS4 send me a message on there and add me, we may have some space to see if we can help you out. It's best to play with a smart team that acts like adults.... our method is with 4 people, you rotate who picks the map, and whatever drops there they get first dibs. If they have or don't want it, then others can take, but we never roll against the picker because it's a waste of time and resources. Playing with randoms will crush your will to play this game, either due to stupidity, loot rolls, or bad host lag, I guarantee it. I doubt there are any high level players that have played an extended period of time randomly.
The suuuucks that you missed the Bloody Mary... if it makes you feel better it's a pretty crummy weapon overall, everyone was excited for it at the start until they got it, and then all agreed Doldren's default KLT is better. But your point still holds, getting blueprints in this game is very frustrating due to not only drop rate, but the horrible winner-takes-all mechanic.
