Having people pay to test the game for an entire year seems like a really bad idea if they want the game to maintain any momentum and have a healthy playerbase. Not that it has much of either at the moment. However it's still better than what it will be once the subscriptions start. If they're really that low on cash, they should just implement a cosmetic-items-only cash shop, then in a year decide if they still want to add a subscription fee or if they should just continue using micro-transactions.
Also, it's too bad that you can't check a server's population anymore. It would be really interesting to see a before and after count for when the subscription fee goes into effect.
I bet a large portion of the people still playing only do so because the game is free. If I recall correctly, the last 2 times they announced the introduction of the subscription fee, they ended up extending the free trial at the last minute. I wonder if they'll do the same thing again if there's a large enough drop in the population. Or maybe they'll just use it as an excuse to cancel the game, who knows.
