Given how stingy the tonic system is and how we only have a month to farm the last 2 weapons for the season, it feels like everything is against players getting the rolls they want for these weapons. Especially since I have a feeling all tonics and resources will probably be deleted at the start of the new season. Meaning if you didn't get that god roll red tape, then you'll have to refarm the exotic mission 1st before you craft the tonics to farm the weapons.
