In mod 14 there are basically 6 different weapon sets available to players with a IL of 520.
The BiS for DPS was primal and the BiS for support was the MC set.
The alternative sets players used included Tyrant in place of Primal, Pioneer in place of MC or Primal, Sun set if you did not want to deal with running CoDG for a 520 weapon and the last set is the Piligrim set for those who ended up wanting to buy one instead of grinding out for seals, hunt lores, material/AD, or CR.
With mod 15 now in play on PC, what weapon set is BiS for DPS and support. I heard rumors but would like some clarification on the weapon set changes in mod 15.
