1. Farming difficulty will not change, it's not hard, maybe a little boring but not hard.
However, I'll seriously think allowing the monsters attack, add some custom instances and make farming a little complicated and not that simple!
2. About custom items and balance: It was impossible to manage creating a decent balanced server with more armors instead of just one (talking about custom items and not retail) and that is the reason I have added .dressme command on L2Chaos (thanks again to L2JSaver).
3. About noblesse there are 2 ways to get Noblesse Status, you have to do the Quest (I have spawned more monsters, it's just a matter of 1 hour to complete it + barakiel) or you can buy the Noblesse Powers item with Vote Reward Coins (It's tradable so the more people we get, the easier it will be, it's going to be a sellable item on Private Stores.) ....
Thanks for your suggestions, let's continue our discussion!
