I never change my loadout for anything, pve or pvp, one mode over another. I change if it's needed for a bounty, but that's it. Right now I'm using a scout, sidearm, and an MG. "I don't fear the man with many guns, I fear the man with just one." To help understand, it's like the jack of all trades but master of none. A player who uses just a few weapons almost all the time for everything, imagine how practiced he or she is with it. This is true for real life as well.
