So I've been doing crucible for a bit and so far everything seems pretty well balanced and sticks where it should gun wise. Scout rifles are jack of all trades if you pull the trigger fast enough. Auto rifles are closer range to medium (maybe a slight impact buff not much) pulse rifles are good if you compensate for recoil. Hand cannons are close range with awesome impact probably the most balanced. Secondaries I actually use like shotguns do what they need to if used right instead of corner camping. And since I don't use snipers or fusions I'm not going to remark. Ability wise I only use titan and warlock with my warlock being a recent addition to the family. Titans seem fine the grenades are good the shoulder charge can be very annoying if used right but I haven't ran into that often. Sunbreaker is balanced out other than the fusion grenade kills after death. Defender can be tricky especially with the no backup plans/invective combo. I'm not going to comment on warlock because I've only used void. But I'm pretty happy with crucible I mean I see a few guns used repeatedly but it's how it goes.
