[Mechanism] Node investment (not an Aprilsfool joke)

I have not found any posts directly related to this subject and therefore I will now post what I have found so far to be true for the "official" version:

According to these links investing in Nodes (any and all) ONLY affects Drop rates (in cities/towns also Amity game) and the droprate is only affected with every 10th mob you kill has an increased droprate of 5-50% (node level 1-10).

This means that none of the ressource nodes are worth investing in, nor the fishing nodes, and to say it straight up you only gain an increased droprate for 1 out of 10 mobs means that investing in any nodes is basically meaningless.

In this light I would be extremely glad if the GamezBD staff could answer this post with the Correct information about how the node investments actually work on our server

 

Worldbosses are not affected by Node investment either.

There might be a Node level at which the game starts giving you less drops say around Node investment level 5 and up?

 

It;d be interesting to know for sure how they work on this server. But that's like that from retail too from what I understand, there has always been a lot of speculation surrounding node lvls and never any concrete proof they actually increase silver/hr.
