dying is part of the game. tell your friends to read some gunner guide or watch gameplay of high level open players and see what theyre doing. or just go to casual corner and hope to pop it, but good luck getting good there without being banned
i dont think it should have full auto. at that point, it becomes a clone of the A280 or the imp variant of that (i forget the name)
making it similar to the halo BR i think would work better for what its supposed to be, as well as having a sniper alt fire.
i think a better alternative would be to just make the ee3 functionally a burst fire gun. 3 rapid shots per burst, the more you fire it the more inaccurate it becomes over time, so that it rewards precision and not just spraying and praying like the e11.
