I think thats a matter of perspective Vulcan.
I log on as infantry and head out to the boonies... I see about 20+ contacts of friendly ground units on my screen and that's just in the 500m 'radar' range.
I look up and I see about 10 or so aircraft, both friendly and enemy fighting it out or strafing/bombing.
I know there are quite a bit of enemy players around since there is lots of shooting between armor of both sides and we are losing and recapturing town objectives plus the chat keeps reporting certain areas swarming with enemy infantry.
I do not see the 100's of people. They are there though. You cant see them because you're not in the general area or simply because your client reaches the max number of objects it can display to you.
Jump on a plane and head to the same town and the sky if FULL of aircraft almost all the time. Planes you did not see when you were on the ground because your client did not assign them priority over the enemy tank 200yds over you. But they were there.
The number of people are there. Peak time is a mess and has the biggest fights ive been involved in on any game.
The max object limit is a big problem but its not terribly game-breaking as it was a couple years back. Back then the game would draw you a bomber 2kft above but not the guy knifing you lol.
Its not a perfect game nor the flashiest but it is very fun for the ground combat portion
