I want to make a suggestion for ATC. We should have IFATC at home on more days. On training server, many planes go to many airports, some planes are everywhere. On expert server, normally 1 or 2 airports have too many planes and other airports have 0 planes. But if we have IFATC at home then planes go everywhere, normal amount of planes everywhere.
I think we should have IFATC at home for half of the week, and special regions for other half of the week. Training server planes go everywhere, that is better. Expert server can also be like that. So people who want to fly on expert server can be free to choose where to go and have good ATC
