As most will have seen, 25% CDR, 20% velocity and 25% range are some insane quirks. No anti-jamming, but this is the most alpha damage a panther can wield in that RA.
I haven't tried this build in Solaris as suggested, but I did do some QP. Some basic observations with very few skill points. Pros: 1. It's tanky for a light. Tons o' armor. 2. Insane ROF. It really dumpsters shells. 3. It's agile enough to get out of danger. Cons: 1. Only one weapon makes you shield hardcore. Combine that with the XL and you pop. 2. UAC jams. Right at the worst time. 3. ROF burns ammo like it's going out of style. Conclusion: It might work for Solaris because the low ammo isn't as much a risk. Combine that with the armor/skill tree and you'll be tough to take down. However as soon as that UAC jams you're defenseless.
