All activities have had the max power of their Powerful Drops increased. E.g. From 500 - 550, A-Rank completion rewards are now +2. Bonus Drops will now drop at a power equal to your completion reward drops. For instance, if you have +3 Bonus drops saved up on Caldera and you get an A or A+ Rank completion on it, that is 4 drops of +2 Gear. Unstable Core infusion costs have been greatly decreased, and the amount of Unstable Cores you get from dismantling powerful drops has also been increased. This is an adjustment made until Unstable Cores are deprecated entirely sometime after Renegades releases. As a way for people to catch up, there is a chest near Zavala in the Tower that gives 777,777 Unstable Cores, and gear drops to bring people up to 300. If you are already above 300, the gear will instead be powerful drops of a certain level, depending on what your current power is. For instance, in the 500-550 power band, the gear will be at +2 power.

I’m not getting those bonus drops at completion level at all - still getting 1 @+2 and bonus drops much lower🤷🏻‍♂️
