Premium account is a NO. Consider other methods supporting the server. You can add an abundance of accessories and costumes for donations. What troubles me the most is the drop and spoil boost in premium. Exp/SP is ok. Someone determined to level up fast won't be bothered by it but drop/spoil give the advantage of greater wealth for premium players and it affects the economy.
Another fail server with 400-500 ppl. In 2 weeks they will have very low population. They didn't advertise the server. They have exp runes and npc buffer till 61. LOL. Waste of time.
