it's as simple as there's a lot of weapons that can drop from each core playlist activity, it's never guaranteed to drop one even if you win, and even if you get the one you want they have a MASSIVE perk pool that makes the chances of getting the roll you want less then 0.1%. with the new Gambit scout rifle that came out this season the Servant Leader I was really excited to try and get one with the roll I wanted cause it's a kinetic rapid fire scout AND it could drop with my ideal roll of Rapid Hit + One For All, it was the PERFECT weapon. However I quickly realized the chances of me actually getting the gun with that roll. There was no point to even trying. very simple math can tell me that with 12 perks in each column and me wanting one perk from each column the chances of me just getting the perks I wanted on the gun are 0.08%, and that doesn't even account for the chance of just getting the gun to drop in the first place or the barrel, magazine, or masterwork. And I get it's not like the odds of getting a god roll on other guns are exactly anything better but the chance to get it on these guns is so astronomically impossible I might as well go try winning the lottery instead. I would love to see some kind of targeted farming system of any kind for these playlist activities like maybe some kind of bounty you can do that when turned in is guaranteed to be a specific weapon or tie it into umbral engrams and let us decode them into gambit, crucible, or strike weapons. Just literally anything to increase the odds somewhat.
