The whole culture of the NOE smash and grab has left the game, with some exceptions from time to time. 250AGL certainly made it easier to be lazy about getting into auto level. And easier to manually follow complex terrain. The few times lately when I see an NOE with at least 10-15 guys, it's a 50:50 chance they get the capture. It leaves me scratching my head how they blow it, but a few guys get in the air, a few in wirbles, and it's bust for the attackers.
When you see a field flashing out of the way, someone usually looks to see what is up quickly these days. It's hard to do an NOE smash and grab with the smaller numbers and everyone looking for an easy fight. The popup off an NOE is usually easier to fight against than a 10 fighter jabo attack from 15k. I do wonder if the NOE alt was put back to 250AGL if people would start giving NOE missions a try again.
