Cleasing the world with the Seneschal feels a bit underwhelming right now. You spend 10 green orbs and world is cleansed.
I am pretty sure most of you already keeping your 99 green orbs for a long time by now and want to cleanse the pestilence yourself for items or a challange. When you don’t want the challenge I don’t think you bother to cleanse it via Seneschal either. You will do it for other day and you just want to play crucible today.
So I suggest make cleansing more expensive maybe per area and give some rewards from it accordingly. For example for a full world cleanse you need to spend all 99 orbs, The Seneschal does a scream thing while shaking his hands or whatever and a small earthquake happens and some items maybe along with some blood and corpses pours down on to room. Maybe he looks tired or wierder afterwards for some reason to discover later. Also rewards are not as much as as if you cleanse it by yourself.
I wish items has their own model as a drop for this to make it more cinematic but anyways. I don’t know the lore about the armors and weapons in the room but making this might add or totally change the lore which is why devs might not be considering this even it is better as a cleansing concept for me and hopefully for some of you aswell.
