How to make halo 5 the best halo

Halo 5 is a very good game in my opinion, but there are several ways in which it can improve. These improvements will make halo 5 amazing.

Gamemodes: add all the old game modes back as well as some new unique game modes. Comment some cool game modes down in the comments

infection
koth
race
team action sack
team doubles
Team snipers
etc.

Add unique maps that are beautiful and memorable. Have at least 3 more covenant maps, 3 Promethean maps, and 3 more war zone maps.

Change the UI so we can view players in our lobby
add special challenges to be able to get amazing armor sets that symbolize something. Comment down below of challenge ideas.

These as are what I think will make halo amazing. If they can they should also add campaign dlc.
Also new unsc vehicles

falcon hornet etc

Well 1/2 of those modes are either in the rotation or are confirmed and serious question would making h5 the best halo a good idea if it was the best halo then h6 and 7 would not be the best

They have to implement these into their playlists.
They need to bring all of the good game modes back from previous halos. Also I forgot to add this but they should put playable elites in wartime and I ranked playlists because then they don’t have to worry about balance. They also need to separate the ranked and unranked playlists, so at the start screen under multiplayer it would show arena, social, war zone etc.

Scrap the current aiming mechanics in favor of the tried and true Halo CE-4 aiming system.
