the first build I thought of using only revenant components for a cheap S7 build. The ammo can be increased to be viable in QP, just take off DHS for each ton.
This is what I've been running in QP for the event. It makes everything think twice about staying within 250m of this mech.
I might have to try this switch. I had put mine up to SRM6A and used just ERMLs in QP but I've been finding that unsatisfying. Perhaps it needs more laser.
