Id rather my team have full rockets to down crota than getting to the point where two people need to fire 3 rockets because the other two are out, let me explain. When using the heavy ammo glitch, not only do you get full rockets(same as a synth) you have at least 4-5 purple drops on the ground for reserve. The problem with synths are that you have to wait 5 minutes to use another. So, since i have a ghorn, i fire rockets everytime we down crota to make sure that i pick up the slack for people who dont have ghorn. That means 4 rockets per sword. After 2 swords i would be out of heavy ammo and still have a cool down to use it again, not to mention that i need to help kill the ogre by firing another two rockets at the first ogre and a rocket at the second ogre. With the heavy ammo glitch i am assured to have enough heavy ammo for all this PLUS another sword to finish crota off. My team can do it the first time almost everytime so for us the heavy anmo glitch is worth the extra minute
