I returned after c. 4 months for Harvest Festival; WDD had launched a few weeks earlier.
And came to realise that there was no spam in world chat. None. Nothing.
Amidst the other stuff there were a few changes that I missed / went unreported:
1. All (new) keys are Black Steel Keys; all (new) loot boxes are now Traveller's boxes. Old keys & boxes will fade away as used.
2. Key Black Steel Keys are only available from the store. No drops. No key rewards for finishing an area.
3. Store bought items can no longer be mailed with mithril coin.
So not only is there no spam from botters there is no spam from people wanting to sell Sturdy Steel Keys.
Its so "restful". Well done SSG.
