After playing halo 5 since release. I have encountered many things I like, and don’t like.
Here is a list of what I think Halo 5 could use/have tweaked.
Customization.
Armour:
with halo 5’s crazy amount of armour, having it all mix and matchable would require a lot of work and use of memory. I think? Lol I’m no programmer.
99% of the armour is made for its matching piece, both by skin and design. But I believe with the ability to edit your arms, legs, shoulders and such. Just like in halo 4, would be a great addition to the game. There would be some really great armour combos! And some not so great ones…
Colours:
I don’t get why we have forced emblem colour combos. Sure it would take a lot of time to make it for each part of the emblem can be coloured by any colour of the selection given. But I think it would be worth it and I don’t see why it can’t be added/fixed in ten future.
Also, the player favorited army green, or “Sage” is absent from the game. As well as its two fellow shades. Can’t see why it can’t be added to the colour selection.
Custom games:
I have no idea what’s to come with the forge update. But I really hope the fun and goofy game types are added. Mainly Infection from halo reach. Please god not that awful flood game type from halo 4. I thought the flood from MCC was cool. But only the appearance. I never explored the options for it. But if the used a proper looking flood model with the same infection options as Halo: Reach. I think it would be amazing.
Also I hope to see odd ball, grif ball and other game types that we have had since halo 3.
Lastly, THE BLOODY SMG!
Through my time playing halo 5 I am countlessly finding my self being out gunned by the SMG while playing warzone. I prefer the precision weapons like DMR, BR and pistol. But even then, while in a medium rage combat situation not only does the SMG prevale, but unless you get a perfect kill with the DMR or BR. You always lose to the SMG. Well not always but a lot of the time… And I overall find the SMG slightly over powered. It’s not game breaking but being killed by the spay n pray wielding noob. While using a BR or DMR just grinds my gears.
I do love halo 5. Although it’s been repetitive to play because of the lack of things to do. It does however keep me entertained for the most part.
I can’t wait for forge and I really hope 343i bring back the missing game types and ect.
now before I get torn a new one, please understand these are simple things I personally have noticed, and or would like to see. So respect it and avoid trashing it 
Do you agree with what I have here? Do you have more to add that you would like to have added? Please reply! As for I’d love to see what other people like and or dislike about Halo 5. As well as what other players would love for halo 5 to have added or tweaked!
