I, among other people, have jobs they have to go to. When i logoff and come back 12 hours later, i tend to get 1 maybe 2 missions. Whereas if i played for 12 hours, i would have 8.
While yes, i could AFK somewhere in hopes of getting more. But i don’t want to leave my system on 24/7/365. Or have my kitty lay on my keyboard and interact (because they love to lay in warn places).
My suggestion is to boost the mission generation when not connected. This will help everyone whether they be alts or newer players or even a main.
