Why the Secret Spell Scroll system would have never worked.

They are still going pretty ok compared to GMS.
Not to mention no 2x cards, permanent NX clothes, lack of duping, fast fixes, useful Tespia server, developpers in the house.

Every version has their ''pros and cons''. There is no best version though. Doesn't GMS have permanent clothes sales from time to time?
In KMS:

- Users have to deal with a massive amount of botters. They just can't beat them.
- Users are still getting hacked. 2nd password system and authenticator don't help these users.
- The massive database leak from last year put Nexon Korea in a bad light.
- Hackers exist except they're rare to find. That's maybe because Koreans don't like to share while American users do showoff their hacks to screw other users over and to increase their so called e-penor.
