You've played something so much you don't know it's name? I don't think that's how that works. And it's not nonsense that's how you play a shooter that doesn't just flood your encounter with your strongest ammo type. If you hadn't noticed headshots melt enemies, especially with kinetic. There really isn't too much need for power ammo, and when there is you should be able to clear whatever is giving you trouble. Get real dude
