Bungie knew what they were doing, raising player health to reduce Hand Cannon and Pulse Rifle ttk, then reducing HC body shot damage, and pretending to buff some pulse rifles by making the recoil more controllable. The changes automatically made Auto Rifles the best primary because of rate of fire for body shots and high damage for crits which is easy on an AR and quite forgiving if you miss your shots, Hand Cannons don't have that forgiveness if you miss. Shotguns and special ammo nerf automatically made SMG's and Pistols the top secondary choice, and the lack of special ammo essentially removed Snipers as a viable option. Its ok, Bungie will probably adjust everything again soon to cater to Hand Cannons and Hunter abilities, they always do.
