@Krupi Yeah, this is true. But that's what matchmaking and newbie servers are for. The average skill level in Il-2 servers is already very high for new players, I couldn't say that it makes all that much difference how bad the equipment a newb has as to whether they get stomped over and over or not when they first start.
In any case, many of these casual players are those who will play single player campaigns and online only against friends to start with anyway.
Like maclean says, often competitiveness is all that people will need to go out and invest in new equipment once they decide they like a game.
