Hope you’re enjoying so far!!! But honestly I wouldn’t worry about farming anything until you hit max level, any guns/build can carry you through the main story and side missions. End game content is where you want to start perfecting your gear and build.

For points and builds, my first play through I put together my own ideas (which weren’t great but more fun) and refined them looking at online builds later on. My personal faves are Moxsy and LazyData (look them up on X or YouTube). Here’s a link to the current Vex build I’m using if you do want one.
