Update 1's upgrade rebalances made the roster be too top-heavy
Many upgrades were pushed from lower tiers into higher ones as part of the re-balancing (most of which I do agree with and think they're good decisions, as those nothingburgers now are actually useful, as is the case with Poison Extraction, for example), however, this, together with "all upgrades are the same tier in a negotiation" made it so that runs now lack a lot of variety.
Reverting the negotiation change would be a mistake, as it did make it feel like everyone was on the same footing during a negotiation, regardless of your place in the pecking order. I think multiple of the upgrades from each tier except for Common need to be moved down.
For example, the newly rebalanced "weakpoint hits move 1 ammo from total to the magazine", which now allows for a bottomless clip as long as you keep hitting the weakpoints, could easily be a blue instead of purple. Poison Extraction should be a purple instead of orange. "50% shatter" should be a green or a white. +1 jump could be a blue.
There's many other examples you could see in the full list. The fact that they took most of the ability cooldown upgrades out of the game, which majorly were white and green, doesn't help with the variety either.
