Light assault gun could use a buff.
It's not a good choice against frigates (kinetics also get shields of any size and do sameish or better against hull, railgun has much better hitrate, needler burst overload).
Killing unshielded fighters is not something ships with ballistics have trouble with.
Obviously not good against anything bigger but that's intended AFAIK.
160 flux/s on a frigate feels too much for what it does.
2. Autopulse laser with s-mod extended mag is busted, i guess it need to be toned down a bit.
It's certainly good, but I don't think it's OP. There's not really any ship on which it dominates the other options. It's a harder sidegrade to plasma cannons on an Odyssey, a very niche early/midgame option for Sunder, one out of many powerful weapons for a Paragon, and one of a rare handful of alternatives to HIL on the Executor. It's good enough to be interesting, but by no means any better than it has to be to be interesting.
I'd go a step further and say it's on the weaker side among the L energies, even with S mags.
Ships using it often get themselves killed with the burst flux buildup, and it has trouble against hull since charges are spent on shields/target switching.
The competition is plasma/HIL/tacyhon lance, it's a hard sell despite being one of my favorite weapons for the style points.
With pulse lases buffed it's even rougher, 2 pulses cost the same OP and have 2.4x as much sustained damage with better efficiency (no burst, -100 range, -50 hit strength does hurt ofc).
Player Radiant is the 1 case I can think of where autopulse can look better than the alternatives.
