These are just some notes / tips I am discovering about the game.
Collecting Resources
Depending on gathering rates set on the server, exact numbers of material yielded will change but should stay in the same ratio no matter what the setting.
If using tools, better quality means more resources are collected per node. Ascendant -> Mastercraft -> Journeyman -> Apprentice -> Ramshackle -> Primative.
If using dinos, higher melee value means more resources are collected per node.
So, you might have a tool and a dino that collects the same resource but depending on the tool quality and the dino's melee value, one might be better than the other. You need to experiment and see.
It should also be noted that even though the Wyvern may not be the most efficient gatherer of specific resources, what it can gather it can do so very quickly, safely and travel faster than any other creature which gives it a major advantage. You can also use combinations such as a Wyvern for fast traveling and protection while carrying an Equus to store cactus sap that you collect using a chainsaw.
