More weapon choices

I wish we got better weapon variation in game. For example instead of the grenade launcher (reach) OR the sticky launcher (4), why not have both in game? I LOVE that we have both the br55 BR and the BR85 BR in halo 5 I wish there was more of that. I want to be able to pick between using the MA5B, MA5C, MA5D, or MA37. I don’t want just 1 generic AR per game I want options. Mayne the ARs are a little too similar but there could be some changes made like give one a faster rate of fire or another better accuracy. Just wishful thinking? Probably. I can dream

I really like the idea and would love to see somewhat of a variation in Arena with those choices too.
