First off, in order to talk balance you have to be top of the card, most of the times, to be able to judge objectively. If you are good with all weapon types, you know which guns need balance and which not.
If you need a clutch, or just plain suck at pvp, you lack the criteria for what is and is not balance.
1. Autorifles were OP, they had longer range than intended, the nerf was stupid since it did't really fix the problem just took the weapon type as a viable option.
2. After this, you could use a pulse rifle just fine, a scout rifle just find, and hand cannons just fine, with shotguns reign supreme at close quarters and snipers obviously at long.
From this meta came several HUGE issues.
A - People abusing thorn dot and TLW glitch
B- People abusing long range shotguns
C- People abusing final round snipers
So bungie goes and makes another weapon patch.
To me, autorifles are viable again, i see top contenders players going with suros regime, hard light in normal crucible, and a bunch of legendary Y2 autorifles.
Pulse rifles are not OP now, but lack their close quarter rival, that was Handcannons, you can still kill at close range with handcannon, but accuracy is crap, and you are better off with other weapons.
Scout rifles are as good as ever, even better without the long range handcannons.
This would not be happening, if bungie only nerfed the RANGE but not the accuracy of handcannons at close range.
And probably will lead to a handcannon buff in the future.
Now, shotguns are only an issue if you abuse long range shotguns, those should be removed from the game, just like the 2 burst kills (high impact pulse rifles) were removed and made low impact faster rate of fire.
Normal shotgun users (found verdict, invective, chaperone, strong bow-D) never have a problem with shotgun nerfs, since they use shotgun as they are suppose to. CLOSE RANGE.
Fusions rifel are just fine, if you think otherwise, try a fusion like the susano of warlock, just to name one.
The rest of the guns are just fine.
