Lol, if you die too much to them, it's because you stand out in the open too much. For the auto rifle to get it's optimal ttk, the enemy needs to be out in the open, try to stand near cover or make them miss. PvP is all about adapting. If you have a difficult time adapting, just wait a season or two, they will change the meta and you can complain about the next meta gun. Lol
