Is that a problem? I guess it's a matter of taste.
I get what you're saying, and that's certainly what more people are geared toward these days than what we've got with the bigger maps in particular.
When the new map came in, I believe they said the Bish rolled it in a couple hours. The nits rolled it in about 6ish after HT reset it manually to put it back in.
You're probably right about the focus, although it does seem to me to show up even in the bigger maps if you happen to get the right half dozen people moving in the same direction.
Personally I don't think a map should last a week. IMO they should last max 5 days so you don't wind up with two weekends in a row hampered by a map you don't like.
Personally I like the ongoing feeling of the bigger maps more than the short bursts of rolling the smaller maps asap. On the other hand it might be an improvement to give people a bit more control over their destiny versus logging in to one of the bigger maps pushed back to 20% of your fields with all your strats at 5% because the night shift was unopposed.
I don't see a play session as needing to win the war every session though. I come in, look at what's going on, and decide what I want to do given the current activity. It could be high alt bomber interception, it could be CAS defense at one of our fields, it could be helping take an enemy field in some way.
One of the things I feel differentiates this game from most is the fact that you log in to a situation. It may be favorable to your side, it may be unfavorable, but you have to deal with it. To me that makes for more varied gameplay than logging in to a fresh map with completely even sides and having the same best path to victory every time. Again, that's what more people these days are geared towards but I think it takes a lot of the flavor out of it.
I also think that's a lot of what is hurting the game's popularity. People want their bite-sized bit of gameplay so they can win or lose and then do the next thing.
