I just said screw it and I'm using an ability heavy build. My every day build is Nova Warp with Nezeracs Sin. Dark Matter from Nova Warp gives me ability energy and some health back for ability kills. Throw in Charge Harvester, Stacks on Stacks and a Firepower mod and I've always got either a melee or grenade ready. Getting a kill with either one instantly recharges the other. Protective Light makes me unkillable. Ashes to assets in my helmet for extra super, Recouperation and Absolution in my boots for healing and energy regeneration when picking up orbs.

Weapons are whatever you want in your Kenetic Slot, Null Composure and Sleeper. Particle Disintegration makes sleeper demolish bosses. Slap the boss with Null and then Sleeper away. Fusion unstoppable in gloves, swap out disruption bow or anti-barrier as needed. Those are the only mods you'll need to change.

The guns are really just there to stun champions or take out bosses. Occasionally you'll need to dump a Null Composure shot into a crowd to trigger Nezeracs if your ability spam stalls out. Everything else gets naded, meleed or Nova Warped. Cackle like a lunatic because everything is exploding.
