I absolutely compulsively reload. Way back since halo CE.
And with juju, every time. Especially because getting a kill mid burst would leave you without a multiple of 3 in your mag.
To further my compulsion, I've recently gotten Jade Rabbit and when I get a kill after triggering the perk to fill my mag, I still hit the button to try and reload. And it bothers me so much when I don't see the animation.
