So, the changes I am recommending are mostly about cosmetics, but i do think that these changes will help Halo Infinite as a whole (please note that these are my personal opinions based on my experience with the game, feel free to peacefully disagree with anything I say.)
For starts, I would like to see a bit of a greater free amount of cosmetics off the bat, like what Halo 3 did with the MK.6 (correct me if I got that wrong) with the classic Chief armor (I know that’s not what its called, its just what I refer to it as for newcomers) and CQB, I believe it would be a healthy change to give player a bit more cosmetic freedom right from the get-go.
Next, we should see a passive way to get challenge swaps after completing the battlepass, as for challenge hunters such as myself, certain challenges can be annoying and would rather not have to deal with them without paying $2 in U.S (which is what inspired me to make this post) I was thinking every 5 games or so completed would grant you a challenge swap, as to make them accessible but not easy to stock up on.
Another thing is that I feel as though the campaign rewards were a little underwhelming, don’t get me wrong the experience and cosmetics we got were well worth the price, but seeing some special and unique rewards in future DLC would be great, and motivate people to buy DLC.
Finally, a controversial opinion of mine is that we should see an altered return of REQ packs, don’t leave quite yet, as I have a way to justify this. How long was it in halo 5 until you got a new helmet without paying extra, for me it was around 30 minutes, with Halo Infinite, it can be WEEKS until you get the trailblazer helmet. I think REQ packs should return and be rewarded to players after certain amounts of wins and NOT buying them, as it can help create a thriving economy of cosmetics for players, without the need to pay, it will help give players more cosmetic freedom and personality. It could also add some pack-only rewards to make people play for cosmetics and give weapons like the hydra a little more color and love. Of course people are going to disagree with some things I have said, especially in this last claim, but I am certain this can help solve Halo Infinites cosmetic crisis.
