It's not always about skill. You are in competition with 11 other people to get heavy, and grenade launchers in PVP really aren't that affective without God rolls. Also trying to find 2 people to kill simultaneously can be rather difficult at times. Not saying it can't be done, it's just frustrating. People who got it before the quest nerf I give mad props to for grinding it out. I never thought solo queuing competitive to 2100 would be less stressful than the rest of the quest.
