It looks like you're new here. If you want to get involved, click one of these buttons!
Here's my idea.
You buy a 30 day sub.
You have 30 "tokens" on your login/character screen.
You click the tokens and one is used.
You now have 24 hours to play with that one token, logging in/out as many times as need throughout that 24 hours.
Can't play tomorrow? No prob, your remaining 29 days are waiting for whenever you want to use them.
At $15 per 30days of tokens, you are spending $.50 for each 24 hour block.
You get all the benefits of the subscription, without feeling you've "lost" your money by only playing a few hours a week.
