Actually, having done the majority of my Crucible quest line post-IB as well as Shaxx weekly bounties that require getting kills with a variety of weapons, I've actually used more diverse loadouts week and a half to two week than I ever did in Y1.
Pulse Rifles are really strong. Like really really strong but not as dominant as AR's and then HC's were during Y1.
Cmon, there's no question both PvP and PvE load outs are more diverse than what they were before. Hung Jury almost never leaves my hands in high level PvE, but I'm definitely alternating the special and heavy slots with stuff like Telesto, Chaperone/another shotgun, couple sniper rifles, HMG, launchers, and swords.
Elemental primaries were never that strong for PVP anyways (besides The Messenger). So removing them doesn't change anything there.
PVE a majority (including you and myself) rung Hung Jury because it's an amazing roll and easily obtainable.
Removing elemental primaries did nothing to add diversity. People are still going to stick to a few primaries they love for PVE, elements or not.
