Switching to Melee Weapon and Melee Headshot Damage

Before 3.2, if you held down the melee button it would let you switch to your melee weapon without any attack animation even while sprinting. After the update, holding down the melee button now automatically does an attack animation first before switching to your melee weapon. This change makes it clunky to switch on the fly land stops your sprint. 

Also, why is melee headshot dmg lower than body dmg? It takes 2 hits to kill from the body(50dmg) but if you land a headshot(35dmg), it will take 3 hits instead. Is this intended or a bug?
