The problem I find isn’t so much the node allocation… for the most part, the level of the area the nodes are in matches the level of the gear that can be crafted with the product of said nodes.
The problem is the volume of the catalyst materials (teeth, claws, blood, etc.) is too low relative to the volume of the node material. It’s workable with a little grinding for one tradeskill, but if you want to keep two tradeskills leveled up it requires either a TON of grinding or buying a lot of mats off TP.
