I think the current premium system could use some changes. Here they are:
Make it so the premium time only ticks down when offline. This way, when a player's PC breaks down or something bad happens to a player themselves, they'll still be able to use premium time. Also, if someone has little free time, they'll be treated as fairly as those with lots of time.
Maybe change the way stats are treated - instead of capping skills at 20 and stats at 30 when premium expires, make it so they slowly decay to that value as they're used, and then quickly increase towards the original amount when premium is restored.
Another suggestion is making it so any skill-related abilities are retained when premium is lost - if a player has 35 masonry, for example, but then premium expires, they'll be able to build stone houses, but at a lower quality.
Feel free to express your opinion on my suggestions.
