I'd go lifetime if I could afford it, but I can't.
And I do think making the travel powers something silvers have to purchase is a bad idea.
Incidentally, I am playing a F2P MMO at the moment, just not CO. I signed up for Everquest II Extended. The only money I've spent on that was to unlock a Silver account, which lets me buy items from the broker (auction house, but I can't sell, just buy) and use the chat channels. Unfortunately, you have to spend money to unlock most races and classes also, and I'm not doing that, so I can't play a Froglok Monk, for instance.
(I am not a big fan of SOE, which is one of the reasons I quit the original EQ years ago, but I have no problem giving them my money one time, just not every month)
