ODST helm from H3 on Reach core

I was going through the Reach armor core helms and noticed that the ODST helm is the one from Halo 3 and not the one from Reach. I get they’re not supposed to be 1:1 recreations, but using an asset from a different game than the one you’re supposedly using as the seasons name sake is odd. On a personal note, the H3 helm is my least favorite out of the ODST helms, which is why I noticed it in the first place. It just looks weird and out of place to me. I know it’s not a big issue but hopefully they’ll replace it with the Reach ODST helm eventually.
