1) More Random Factor please , similar of FFXI , in fighting a boss or normal mobs they act randomly and they execute random weapon skills on us . Also I would like to see more random NM in the open world that has random factors to make it appear , it will make things more interesting this way. And to make things more fun make random drop rate !!!! <people will hate this lol>

2) Mercenary Quests from Players to Players , questing things to be done for them in return they give something in return but I dont know how you can implement it but it could work with the current system of Steam offline trading ? if you can have a look in here
