I log in daily still, but for fewer hours on average compared to S6. The hours I am on are often idle.
I spend more time Doffing now than anything, it is the only way to get fleet marks, which the fleet just can't get by grinding or working as a fleet anymore.. ya, great design decision there.
My guess is the fleet logs on a lot less because of the same issues, they can't really achieve anything, can't max out dilithium, can't put in a serious dent into fleet marks.. so if you can't achieve something, why are you playing? Despair is a huge factor right now.
