Mainly because of the quest to get the IB armor. Don't force people to use weapons they don't want to use like fusion rifles. Everyone's running Erentil / Recluse cause of the quest and its super annoying also getting old reallyyy quick. I didn't have fun doing it at all.
In the future dont make weapon based objectives for PvP...
Also wtf is up with these laggy players
The only issues I has with the quest were how it did the steps. I have no issues getting X kills with Y weapon but you should be able to do all concurrently. That way you can adjust load out based on random map and play to win the match. Not just play to get a kill with this a specific weapon. Or better yet make it so you need so many kinetic, energy, and power kills.
