The only ones I particularly dislike are the Boltok and Markza. The Boltok because 4s was, to me, literally perfect as it showed how bad the dispersion was getting the faster you fired. Whereas 5s doesn’t and still has the “hidden” dispersion value making shots go nowhere when you have a shot lined up straight with an enemy sometimes.
The Markza, mostly because of its “hidden” dispersion value that also makes shots go to random spots despite being aimed right at a head while not being reflected in the reticle much.
Guess this is kind of also taking a fit at claiming to implement “more modern shooter mechanics with recoil”, but still leaving stupid dispersion patterns that add nothing to aim to certain supposedly more precise weapons like the Boltok or Markza.
