Thank god they are going to buff these drop rates in Reckoning in a future patch- I just hope that they buff their RNG drop rate in Prime also. In all the games since the 2019 Solstice armor has come out, I have received 17 combine Synths and 0 weapons. Note that, to get the synths you need to accomplish particular feats in Gambit prime that also have a chance of dropping the seasonal Drifter weapons. That is terrible RNG and definitely needs fixed.
This weapon pool has some of the most interesting weapons/rolls in the entire game and it is a shame that they are behind some of the worst combined RNG odds in the Annual Pass.
