You're not crazy. You bought a video game that has many styles of play and you are doing one that you enjoy.
Real time stuff is the best part of the game, no doubt. But lack of free time and junk makes it tough.
But since there are no real wolf pack type attacks there's no need to shadow for a long time.
Unless you are waiting for better conditions for attack.
Or unless you are near enough to an Axis airbase and want to see if planes will come to attack the convoy.
Or unless you just have fun doing it
