Bungie, it is way overdue for the powers that be to add an ammo synth cooldown timer and hot use buttons to the player HUD. If you're in the midst of a firefight and you have to stop, open up the player menu, and then pop an ammo synth, it could be a life or death decision. How many guardians must pay the ultimate price before you correct this injustice? Many Bothans have died to bring you this information. Please use it for the good of all. Regards, Killed Ya
