In warzone, everybody would be given all base weapons (assault rifle, magnum, smg, dmr, and halo 2 battle rifle) and could gain new variants through commendations such as kills, headshots, double kills, boss takedown, etc. and maybe use less weapon variants that nobody is going to use because of we had to unlock all 30 something variants, that would be kinda weird.
I strongly disagree with the idea of making loadouts and/or their attachments unlockable through progression in any way. It's pointlessly unfair to new players, and it provides no benefit other than to create more stuff to fill the req pool with. If a Halo game is going to have loadouts (and whether they should in the first place is debatable), then they should not
have to be unlocked from progression and should be available to all players from the beginning, in order to give everyone more equal starts and not needlessly give veteran players even more of an advantage over new players.
And if you're talking about unlocking req variants and not loadouts, then I still don't see the point of making them unlockable from commendations. If those commendations couldn't be earned outside of PvP, then you'd be leaving firefight players out of the fun. Everyone who suggests this idea seems to be forgetting that firefight players exist. So do you want all the weapon variants to be unlocked just from getting AI and boss kill commendations? Really, why even make it so complicated? I've gotta say, I'm not a fan of this idea.
But there shouldn’t be too many, as to not widen the loot pool. In response, some or many armors and helmets that were not well received and clearly not worked on too hard.
Here's a fundamental problem with this idea: why would 343 choose not to widen the loot pool with tons of filler crap? If we keep the req system but only slightly change it, as this Youtuber is suggesting, then what reason does 343 have to cut down on the sloppy armor and identical visors? Sure, it would be great if they did, but as long as there's a req system in any form and microtransactions are involved with it, I can't see them doing that.
For that matter, how would this solve the problem of the req system giving 343 a monetary incentive to favor Warzone over other modes such as BTB? Sorry but I disagree with this Youtuber; I think it would be much better if the req system were trashed altogether. I won't disagree that 343 "needs a win" but how about they get their wins in less intrusive ways?
