Short and quick blog post this one coming as it does after the main post earlier about the interesting gem slump:
No, there’s no resource nodes. Something else will take the place of ad-hoc, holiday content on the go. There are new crafting recipes, but the components for those will come from the rewards gained by playing any holiday content.
This is the forum post in question. Very interesting! No new resource nodes for the event. Is this something they've learned from candy cane? Will candy cane be the only resource introduced in this way?
I just don't know!
Also the recipes added (confirmation there will be - it was kind of obvious but we didn't know 100% just yet) will use rewards from taking part. This means that active play (gaining these rewards) will be the only way to stock up on this wintersday resource.
