What are some things that have NEVER been in HALO?

Give me all the things that you would love to see to revolutionize Halo. Or all things you would like to try out in Halo as a Spartan.

I don’t know, I have some random ideas I guess, not really my own, not really things I particularly want but wouldn’t mind see tested.

Ziplining.
Boats and Water Levels*.
Murder Miner’s wall jump.
Being able to use the direction pad to call out enemies, so people without mics can still communicate somewhat.
Instead of bloom, have it where aim assist decreases the more rapidly you fire.
Icons above teammate’s head to display their health.
Scarab Assault gametype.
I’m honestly more or less fine with charge, groundpound, etc. I just hate sprint.
Shorter thrust, able to shoot while performing it.
Being able to make maps with a PC editor and have people download them in-game (which would finally allow modding as well, as many things are tied to map data).

*(No Swimming, you simply sink into the water, and either walk along the ocean floor or sink into the abyss and die depending on the map’s specific design).

idk, 343 pretty much got what i was wanting, CLAMBER, i hated missing a jump by a toenail
