It's tedious busywork. It's fun to shoot the enemies but that's about it. It's just going around in a circle hitting nodes. The nodes are randomized so it's a crapshoot whether you find one that has something you need. Once in a while a legendary node pops when the weather changes but unless you're making expert crafts (which are too much to bother with for me since they're good for points but not that much better for scrips) the only point to collecting them is toward the achievement for doing so.
Tbh I've been buying most of my mats on the mb. I hear fishing can be the fastest way to get scrips/points gathering though and I have yet to try that. Otherwise just buy/farm your own mats and stick to the 2nd highest tier craft which is easy to make.
