A big thing I do appreciate about EG is the fact that a lot of maps seem to be more ground forces + chopper heavy and friendly but no set of 4 planes flying around dog fighting the entire time without doing anything else for the team. I really feel that since BF1942 there hasn't been a real good reason to have jets in a BF game, mainly because they're too quick and not able to do much for the objectives.
Don't get me wrong, a good pilot can still do some useful things, but lining up the right angle for ground forces is still time consuming.
As someone who main's recon, I am a bit biased, but the map design from that perspective seems ok, some of the vanilla maps were far worse for others than what EG has shown me so far. Caspian is still probably the most sniper friendly map in the game, a lot of other vanilla ones too. EG has the big open fields, sure, but there's nothing stopping a tank from seeing the scope reflection (still one of the most bullshit mechanics ever, even in a dark room or the sun behind you its glowing like a flashlight) and firing a shell at your face, especially since once you're spotted, that open field/hilltop puts you at a pretty bad disadvantage.
