The radar without delay offered GVs and airplanes the ability to project the time of an expected air attack. That is now gone.
With the deforestation of the maps, the distance between hiding places is very large at times. Timing of an approaching fighter or set of bombers is very important to allow time to hide. Harding of the ammo bunkers just makes this worse.
On storchs. Often what is often seen is the enemy icon not the vehicle itself. Same with fighters and bombers searching for GVs.
The number of full-time base defenders is ever increasing since it is the safest, and most point rewarding for those that are points hungry.
Attacking an enemy base takes a lot of time as well as high risk with radar delay, hardened ammo bunkers, short base-town defending spawns, and full time defenders. This hurts the action in the game. If no one attacks, game over.
