Higher quality games with big hosting fees aren't going to be free. (Unless you mean at all and not per month, in which case, ya.)

"Worth it" really depends on your value of money and time. I scoff at $15/mo. So if I played some mmo once a month, I'd still leave my account up. If you make like $22/mo, then of course your $15 is going to be a little more precious than mine.

Still, I think that a good game at $15 is better than a bad game at $7. Not to say WoW is a good game. I never really cared for it. I'd suggest signing up for Mythos beta. It'll be "free."

What is it they say about silence being golden?
