Considering pretty much everyone did the Icebreaker heavy ammo glitch in Crota's End during the Heavy Ammo drought - I'm okay with this. There was also a similar glitch with Sleeper Simulant people used to use. This to me is on par with getting full ammo with "it stared back" and then change the perk to do more damage @ the cost of less ammo while not losing current ammo. It's not like they did a glitch to despawn adds or freeze the boss.
