And yet, WoW's model has proven imminently more successful than what ArenaNet is doing. Time will tell in the end, but there is plenty of speculation that ArenaNet's going down the path of many other "good idea, poor implementations" like WAR and so forth.
Ultimately the issue with another sub game is that the people in WoW are already invested in WoW. Asking them to pay 15 bucks for the pleasure of starting from scratch for a buggy, first release MMO when there's something more mature, still active and developing is insane. That is the only reason another game cannot take the world by storm with a subscription and the clones asking for a fee fail.
Exactly. And it's because $15 a month doesn't look like a lot of money for the entertainment they think they're getting. GW2 is not charging you any of that money though, and because of that, they are putting in more gold sinks. But those gold sinks are not game breaking or takes away from enjoying the game. It is just the perceived notion that they take away from player experience. But the fact is, it doesn't take away from their experience. They just think it does, because basically we're spoiled to get everything so easily. Those spoiled kids can purchase as many gems as they need. I prefer the gold sinks, even if they were to charge us a monthly subscription.
Why do you want GW2 to be successful like WoW? It's better that it stay in its nitche space and stay free forever.
