I disagree on most points. Speaking from experience, two weeks was not enough time to get a feel for this game. Many of your paying customers have jobs, families, and other activities so the two weeks are mostly wasted because they can't play it everyday for two weeks straight. Plain and simple. That coupled with the steep learning curve and seemingly overwhelming number of planes and options takes time. I'd say for most players the two weeks averages out to a couple hours a day for 3 to 5 days.
Opening up the main arena with the ideas I posted previously would increase the numbers in the MA and allow more cannon fodder. Even if they don't buy a subscription higher numbers in the MA make the game look better, it won't look dead. No new player wants to take the risk and pay for a game that looks dead or dying.
Minimize your risk of loosing current subscribers due to opening up the MA with a free option by implementing free user restrictions like I posted above. Limit the planes, limit the radio, no perks, no voice chat, no squads, limited planes rotate and are not static, disallow country swap, limit certain airfields to no free players, etc...
I don't see how this would not increase the numbers and breath life into the MA.
If you're not interested in a small investment of time and "coading" to try and get more paying players, at least you would be making your current subscribers happy with a more target rich environment.
Increasing the amount of free time would not increase the number of subscribers, if a player is not hooked enough after 2 weeks to pay $15, then another 2 weeks will not get him to fork over the $15.
So that leaves the question what to do with the people who would still play, but are to cheep or cant afford the $15.
1. Opening up some free stuff to them in the main could possibly be a benefit simply to create fodder for subscribers.
2. Keeping them around long enough until they can afford AH could be a benefit.
3. Providing a non paying method to continue to play could also loose some potential new subscribers.
4. Keep them around but figure out a way to extract a lesser amount from them with out damaging the current inflow of new subscribers.
But remember 75% of potential customers are gone after 30 minutes. Nothing posted above would have much effect on those people.
