Make a Dungeon tahts has a Classic/Old School Stats like if anyone enters the stats reduc to 90% also pets.
And Maybe Easy/Normalhard Mode also Adjust Levels so even Low lvl can Enter with Party.
And for those Mode It can Drop / Typ Shards or new stuff ( Ofc if only at a boss )to create maybe a extra Slot Item taht can be awakened for this Dungeon. And the dungeon it self give alot exp ... alot alot exp means more than Sky.
Taht will create a Content taht people will have fun making a Party again.. like playing all dif chars again and not just OL!!!!
And call the Dungeon the Judgment xD
