Someone else already posted appreciation for Archaeology but I like how you'll always have something new to explore or a new spot to dig at when you level up. It's a little slow to begin with, yes, but once you get those qualifications things get much easier. Found that an augmented and perked imcando mattock worked wonders too!
Enjoyed getting to 99 and might get around to 120 eventually!
It's also a nice skill to AFK! I just finished 24-200M a few days ago without restorations. AFK and profitable! What more to ask for?
Good luck excavating!
Life is like a camera: Just
focus
on what's important,
capture
the good times,
develop
from the negatives, and if things don't work out,
take another shot
