At very high rank you see:

Weights:
Charger - 1000
Runner - 1000
Flamehawk - 1000

New stuff weights:
Tech collector - ~740
Assassins - 700-1000 (assumption)

Therefore, the rare "dilution" from commons has changed from weight 3000 to weight ~4500-4700, meaning that rare planet drops need to spawn 50% more than before to get to the effective spawn % they had before. In other words they are less common today than they used to be without adjustment.

+1, troop carrier spawn rates for me went from 1 in 300 to 1 in 650-700
also, how many NPCs did you have to kill to calculate the weight of the NPCs?

Enough to be statistically close.
