Question regarding nodes

Hello there,

I've been inactive for quite some time, and noticed that the game engine is quite new, like new LoS system etc. etc.
I was wondering if the nodes have been changed as well?
Nodes = Mines, Herbalism.
I had a could say rock solid herbalism farming route, throughout the years I've never seen anyone farming that route, and now I've collected around 8-10~ nodes from the whole route, whilst before I was getting around 30~ stacks of herbs from 1 run around it.
So I'm wondering, have the nodes been changed totally?

Thank you in advance!
Regards,
Aloisa

bump, could really use some info regarding this matter.

bump, still not clarified..
I'm curious in what has changed exactly since I don't have the time to test it, thanks in advance.
