I got to fabled 2 not by using hand cannons but by fusion rifles, wardcliff coil, and shotguns. As well as some hardcore carrying by my team mates.
Now I want to finish my Luna's Howl quest which requires me to use hand cannons.
I suck and I'm sorry for the comp matches I'm about to lose for my team.
I've already received hate mail over this.
Get 2x Trust: Use Trust A with explosive rounds for the Solar Kills required; the, use Trust B, i.e., the other one - without explosive rounds for the Critical Kills required. That and Bygones is a goodly combination, I found...unless you plan to do your Revoker Quest at the same time, if so, get a Primary Sniper to do it - there are a few to choose from...
As for silly people who send silly messages - it's par for the course; so don't let it get to you.
Play your game but also, if possible, try not to drop your team in it by just focusing on your needs.
Anyone who has Luna, who is not a card-carrying Member of the UTube- / Streamer- / 'Paid Carry-' Brigades, has been through what you are / will be, going through - so ease springs, Guardian, and crack-on! Good hunting!
Cheers!
