we will be opening two servers, one a bit more unserious than icechaw (with teleports to areas from temples and perhaps trainers too), and another with slightly lower experience than softcores. Donations are always disabled on our servers in the first days, but we will try to limit the benefits of donations even more so it doesn't get too unfair for players who don't want to donate. I don't think we will demand players to pay for premium though.
The main reason why we don't get new players on our current servers is because new players see that there are very high levels on the servers already and have no chance to become one of the more powerful players. For that reason it is also possible that we will set a max level limit on the new servers, that limit would be set at some level where we know players are only using cavebot to gain more levels.
