Vex Myhtoclast.
They thought they nerfed it, ruined it. But I used it in crucible. I went positive. And I'm sh*t in PvP. But with the perks I roll on it, I'm able to control the recoil surprisingly well. Don't tell them. And I ran a few legacy strikes with it. It's still great. Just watch out for primary ammo. It runs out of it real quick
My Warlock has an Omolon Uffern HC4 hand cannon I got from an armsday order. Got LitC, Rifled Barrel and Firefly. So smooth to use and just all around useful. Absolutely love it. Probably my favourite non exotic yr 2 weapon.
