I have a view on this too.
Since Forsaken RO, renewed the items which are dropped from the treasures, WoE is a bit more attractive.
As you all know that is not a complete set.
So my new WoE idea is 4 Castles, Unique drops, the Location (prontera, aldebaran, geffen or payon) is each week different and so will the gears. After that week, the guild keeps castle, but it can't be taken, neither will it give treasures.
It gives Unique treasures in the week that it's available.
We already have helmet, aura and wings, so the other Castle drops could be, armor, boots and cloak. Which would make an Unique and new WoE set.
The droprate will be lowered for all of the set-drops(including the current ones), to make it more balanced.
Hard working guilds will be rewarded for their efforts.
Maps are yet to be decided (but I have a few in mind already).
It now is up to you as a player to either agree or disagree with my suggestion and if possible give a valid reason.
