Commendations are missing??

So upon indulging in my weapon commendations I noticed the traditional rocket launcher got a commendation and unique rewards but the traditional battle rifle, magnum and gravity hammer did not get their own commendation and unique rewards…

Why is that? Doesn’t feel right…

it seems when they added the new rocket launcher, like you said they added a commendation, but my guess would be they just gave up on adding them in, the only logical reason I could see for it, is because the Halo 2 BR and CE pistol for example, in Warzone are legendary REQ’s and would be harder to come by, and by that point they may not have all been implemented into Arena maps.
Otherwise it was either an oversight, or they just thought it wasn’t really important to add, and being a hunter of commendations personally, I’m not complaining
