WotLK Question regarding nodes

[Aloisa]

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