There's a big difference in F2P versus paid account. Many things available to the latter are not available to the former at all. And where they are available, they require the expenditure of real world money to acquire.
I wouldn't be surprised if the reason SWTOR is more profitable now is because most F2P players are speding some extra cash to have a little bit more than the bog standard, which is at best annoying.
Now, I'd pay real money if SWTOR, or any MMO for that matter, were to decide to do away with the "Can't get There From Here" syndrome. If you play MMOs, you'll get it.
