The last time i really enjoyed playing Lineage 2 was on a C6 server with features like these back in 2008.
Oh man i miss those days!
The Nobless quest and the blessed RB jewels will give the players an extra and really nice PVE experience instead of non-stopping PVP.
Another plus of the Nobless quest is that some players will gain some further knowledge of the game becuase most servers sell the Nobless status in farm shops.
Also, i liked what you did there with the vote system, seems pretty legit.
One last thing i want to mention is that i'm really looking forward to participate in this TVT event.It sounds pretty fun.
That's all i had to say.
Good luck!
