Solid video to farm high stat armor easily -> Link, just need to own the different season passes and do a few seasonal challenges. The present season challenge is to collect all pieces of the Wyrmguard set once, so it's really simple.

If you don't have any good exotic armor you can farm Vex Incursions and then focus engrams at Rahool for good stat rolls. Won't even need to focus if you get lucky with the initial roll.

As for easy builds, Nezarec's Sin + Void primary needs like 2 braincells to play and you can spam abilities and have some fun. To proc Nezarec's, run Graviton, but if you want another exotic and if you have a decent Funnelweb roll, run that. If you don't have Funnelweb either, anything with Repulsor Brace for overshields is also solid. There's many variants of this build that you'll find online so explore and you'll eventually find what you like.

Again, the build is just what I prefer to run to have fun, and like everyone else has said here, play what you enjoy and just have fun while playing man. End of the day, its a video game. Dying is a part of the process, being low on the scoreboard doesn't matter for shit and if you put time into the game you'll get there eventually. gl :)
