What Changes Would Have Been Acceptable?

I’ve been thinking about the way Halo multiplayer has changed since the original trilogy, and the backlash that followed.

We talk a lot about how the addition of Armor Abilities, Ordnance Drops and Loadouts have negatively affected the core of Halo that had been well established, and was the one thing that should have remained intact.

But let’s talk about examples of changes/additions to Halo that absolutely would be acceptabe.
All you guys who are against the core being broken (myself being one of them), what changes/additions would you like to see in future Halo’s, with regards to multiplayer?
