Ok I'll throw my two sense in this...
There are two types of football players. Those that want to run up the middle, and those that want to play-action pass. Those that want to run up the middle pride themselves on physical ability, Blocking technique, and running ability. Those that want ot Play-action pass (fake the run up the middle and throw a pass to a wide open reciever) pride themselves on being smarter.
The MA is the same way. There are those that pride themselves on their ability to come across another pilot regarless of the plane matchups, E disparities, and number disparities and come out victorious...demonstrate thier skills as [cartoon] pilots. There are those who want to pull off ever deeper and daring raids into enemy territory without being discovered...prove how smart they are.
The skill people are easy to satisfy. I think the issue is with the latter. The radar settings force everything to be a full frontal confrontation. But this doesn't eliminate strategy in the game, it transforms it from figuring out how to 'fake out' the other side, to organizing the proper resources and executing a well thought out plan to accomplish an objective. Which should be a great thing to do in a war sim.
The "fake out" guys are getting pissed because they can't do "fake out" base taking anymore, because with radar covering the whole map, bandits are drawn to you like moths to a flame.
Would changing the radar back really fix the problem? I say that's a matter of perception. The reason you could sneak a mission in the past is not because your plan is clever enough to have faked anyone out, it's because no one cares. It's not worth the time investment to fly around looking for a few planes that might be trying to capture a meaningless base. So the percieved cleverness of your part is nothing more than the result of it not being worth the enemies time to look for you.
It seems the choice has been made by the game developers to promote action per unit time for paying customers. Not hard to figure out why they made that choice.
Perhaps you can change your definition of being stategic, from faking the enemy out, to planning a raid that can capture a base with a handfull of very organized friends or squadies, knowing that the enemy will see you coming. Just a suggestion
