Not sure if this is bait, but forget that. Incase you're for real, Sidearms are the new special weapon type being added with HoW. From what we know, they have very high fire rate, stability, and reload at the cost of shooting the impact equivalent of marshmallows. OP is complaining about how much ammo they have, which is a decent amount from what I've seen, and that they should be primaries because of said ammo count.

Oh, ok. Thank you! I honestly missed twitch stream and/or update that revealed sidearms, so this is my first time hearing about them.
