Desired & Undesired Things for Halo 6

As we look forward toward the eventual release of Halo 6, I know there are varying degrees of anticipation and dread when considering the future of our beloved franchise. Some hold that it is in great hands, some hold it is already “dead”, and others still are stuck somewhere in the middle, just wanting the games (and the community) to be better than ever.
As such, what I’m asking is that separately for campaign and multiplayer, post the top three (in any order) desired and undesired things you want to see in Halo 6. I’m asking that you don’t just say things like “bring back Halo 2 multiplayer now!” or “undo Halo 5” or other such mindless responses. Instead, formulate your ideas carefully, considering why you do or do not like specific aspects of previous games, and state those reasons. So, instead of stating “bring back Halo 2 multiplayer”, instead state something like “reintroduce an in-game clan system, including clan matchmaking”, or instead of “undo Halo 5” write “resolve to prioritize all characters and their story”. The whole point of this is to give those in charge of our beloved Halo something constructive and useful to build off of.
Furthermore, if you come across a point that you want included, try and figure out a specific method by which 343i can/should satisfy that desire. Likewise, if there’s a point you feel strongly shouldn’t be in Halo 6 (implying it is or has been implemented in the past), I’d ask that you consider what it could be replaced with or how to remedy the wholes its removal would cause. Please place all of these methods/implications in spoilers underneath the main point. Not every point will need this, but be as specific as you can in what you want done/not done, and how to properly bring that about.
This isn’t the place to just rehash on the strengths and weaknesses of past Halo games. That information is extremely useful and needed to make the future of Halo what we all want, but this isn’t the home for that (I’ve created a topic for that here). Instead, this is the place to give insight into what you’re looking for in Halo 6 that will make it stand out as not just on par with other Halo games, but the best Halo game.

Things to note:
Please refrain from discussing the game’s music. We all understand the direct emotional connection the music can have to the gameplay, but we need to stay focused on the task of the gameplay itself.
Please keep in mind that all of these are opinions. The point of this topic isn’t to debate opinions. This is just a stage by which to present your own opinion in a constructive manner. Keep things positive.

As I said in your other thread, please use one of the existing major “Halo 6 wishlist” threads for this type of discussion.
