If the squad leaders, support and commanders are doing their jobs properly by placing plenty of outpost spawn points and garrison spawn points, in the right positions, then you should never need to run too far. Unfortunately that learning curve you mention means that most people run and gun like its Battlefield or CoD rather than adapt and play with proper teamwork and in the proper way. Hell, there are still a HUGE number of people who think that you have to get into the circle to cap a point (mostly due to other games having it so that you have to get into the "circle"), which results in people running into the circles and being all bunched up and easy to kill en masse, instead of capping the point while remaining outside of the circle.
There is a diffference between being in a sector and being in the circle on the map. The circle on the map is a strong point and will doubles a soldier’s capture value. So it is worth being inside the circle, obviously not if you are all just going to die though.
