Ideas and suggestions
I am a relative new Player, coming from PoGo (which was mostly for my children - Never had any PoGo in my past - Only level 30), and HPWU - Which I liked better because I could relate to the story - But soon got boring.
Found out the easiest way to get new pokestops / WU Inns was Ingress, so I started there. Now I am level 8, and on the way to level 10. But I really like the game, and the excercise stuff is healthy, but I must admit to driving small extra trips on way to work and back.
One thing that annoyed me as a low level player was playing under someone elses huge Field, really limits you. Now I can take them down if the corners are not that far away. Even as level 6, I took down portals with dual aegis shields to get points. Now, if fields decayed faster depending on their area, we would have a different game, better for beginners in many areas. 100km2 could decay in half the time. Or maybe make it dependent on the length of the sides. It is easy enough to take down portals. But getting there poses a logistics problems for people without a car. So say 1000+km worth of sides would last 4 hours only without more XM. Or maybe that would help the Recharger medal too much ?
The other idea is about rural portals. We have too few of that. Including our local forrest/park popular for walk/run/bike. We need relaxed requirements if a portal submission is say 500m from the nearest portal. Or if Niantic could add road crossings, or other things automaticly, like local hilltops etc.
Or local forrest just touching city limits has 4 portals in a 2x1 km area. All 4 near the asphalt road through the forrest. One of them is just in a patch of forrest, no manmade object there (except the planted trees). But I am not going to try to get it removed. You need to exit the car to get in range. Roadcrossings in such an area should fine, or natural features like a big boulder, or a named hilltop. The red wooden gates blocking car entry is a candidate, but are near the roads. I want more in walking distance. These are great as anchors, as they can live long, as most players do not get out of the car.
Been doing lots of orienteering as a child (running with map and compass), so for me finding natural features are part of the trip in the forrested area.
