A few people during my trip through completing the Steel Path were curious about my kitgun. I made this in response to "the last straw," being the last person to ask about it.
Pretty simple, I think. Barely have to aim, though you [Sacrifice] headshot damage capabilities just by the nature of the Vermisplicer.
The only caveat is it is best to change elements based on the faction, of course. Been using Heat/Corrosive for Grineer, Electricity or Radiation/Viral for Infested, Gas/Magnetic for Corpus, and honestly, the Radiation/Viral mix works in the Void for me. I've also been playing [Nova] a lot, but, I've noticed that I could easily go back to main'ing [Nekros] with no trouble. [Nova]'s merely for progressing through Steel.
