It was something that bugged me from the beginning but now that many things have been fixed, it's the one that catches me the most. But maybe I'm missing something; maybe I don't use scouting as it's intended. The following post assume that there is no other way than describe; if there is one, then consider my suggestion canceled.
I have to manually scout each turn if I don't want to lose my "scout power". So I need to build many scout stations and use them rarely if I want to have a fun scouting: not being bothered by it while I do something else, and being able to scout a large area each time I care about scouting.
The easiest path to fix it and make scouting fun (to me, at least) is to stack "scout power" over turns and being able to use them all in one turn. I understand that an infinite scout stacking would be broken. My suggestion is to have, like crowns, a scout "income" and a stack. The scout station produce 1 scout per turn and after 10 turns not scouting I would be able to scout 10 times in one turn. The stack would have a limit, like the number of scouting planes ready to go for a mission. There would be sort of civil airports or plane warehouses that increase the quantity of "scouting missions" available at once, and the scouting station would supply it (build planes, refuel, repair, etc).
For example, I just build a scout station that produce 1 scout and can store 1 scout. Each turn, I'm able to send one scout mission, like it's possible now. Then I build a plane-warehouse/civil-airport/etc that can store let say 10 scout planes. Now I can wait 11 turns, send 11 scouts in one turn, and go back to city business for 11 more turns. Then I can build two more scout stations and send 12 scout missions every 4 turns. Then again I could build more airports to send more of them at once but with more turns/time between each pack of missions.
Maybe these numbers are a bit overpowered, but the core idea is here.
EDIT:
I just find that scouts are automatically sent if they would be lost. This may be new because I didn't noticed earlier. Well, it solve the problem of losing "scout power", but autoscout doesn't feel fun either because I can't seek something special and I'm not there when something fun is discovered. I still feel that a stacked scout mechanism would be both more fun and more streamlined.
