Currently, the Premium only works for 30 days, regardless of you logging on, waiting time etc.

I propose Premium be changed into credits. In which, say you buy 30 hours of premium instead of 30
days pass. This is so that players who do not wish to spend that much may still play premium.

Another suggestion is that the, say 30 hours of premium you purchased only considers when you are
in battle (not missions or any other battles outside Area 7), so that you can take your time to play. I
don't buy premium because I know that I have to play hardcore so that my 10$ doesn't go to waste.
Also, since 60% of the time you are NF is actually waiting for balance, only 40% in reality contributes
towards your extra premium gain.

So to summarize:
- Have a "credits" system
- Only count the time inside battles
