The increase in gray mod drops happened when they switched to 100% drop rate on mods. The drop rate for good mods stayed about the same but you got a lot more junk to go with it.
I don’t have any reason to believe the proportion of speed secondaries has decreased.
Mod recommendations are just there as an option for people who don’t know what they are doing and want something quick and easy. If you want good mod choices just pretend that feature isn’t there.
I would like to see an increase in the storage cap and I would absolutely like the option to immediately sell mods wherever they appear.
