Unlike my other post, I will be polite and rational with this one. I will just be naming off the flaws I see with Halo 4, and offer possible solutions and suggestions to said flaws. Feel free to let me know what you think and what you feel should be done to make Halo 4 a better game! Though I will say, please keep it polite and helpful, I know I can’t force people to not post things like “343i is a terrible developer and this game blows”, but it’s greatly appreciated if you refrain from doing so! 
Issue #1: Custom Classes
Personally, I don’t have much a problem with this, but there are a few things I feel should be improved and tweaked. Tactical/Support Packages(Perks). It’s not their existence that I have an issue with, it’s just that a lot of them seem rather useless in many situations. I’ve found that ammo and mobility tend to be the most useful in any situation, but that could be just me. And spawning with plasma grenades. This is a big no-no. I’ll admit, I have them in two of my classes, but those classes are for maps with no vehicles. And the DMR. Oh boy. Such a touchy subject. I feel it should be nerfed in regards to aim assist and bullet magnetism, or reduce the damage and fire rate.
Issue #2: Lack of smaller maps
I’m all for BTB, but some more variety would be nice. Since it has only been about 6-7 months since Halo 4’s release, and the War Games Map Packs have all been released, maybe you could put out some map packs with more focus on small-to-mid scale conflicts?
Issue #3: Campaign
Again, not much of an issue for myself really, but there is one thing that could really be done better. I’m sure a lot of newcomers ended up completely lost in regards to the Didact and Librarian, and other things such as the Composer and Genesong, which were only featured in the books, mainly Greg Bear’s The Forerunner Saga series. I liked the focus on Cortana and Chief’s relationship a lot, please keep that! All I think that should be done is make the story more accessible to newcomers.
Issue #4: Spartan Ops
I’m a little torn in Spartan Ops. On one hand, I really like that opening sequences, and the narrative-focused gameplay. On the other hand, I HATED replaying the same areas again and again. 1-2 times, I can do. Maybe 3. MAYBE. But anymore, and just… no. Also, don’t keep infinite respawns. I hate seeing allies just constantly throw themselves into firefights on Legendary because they know they’ll just come back. Maybe have a set amount of lives, like in Firefight?
Issue #5: Gameplay recording
Ok, this isn’t really an issue, it’s more of a personal desire. I would absolutely LOVE to be able to upload gameplay straight to YouTube. Dirt 3 does it, so does MW3, so why wasn’t Halo 4, which was newer, able to do it? Not everybody can afford capture cards, so I think it would please a lot of people if that feature was in-game. Also, campaign footage in Theater? Yes please.
Issue #6: Competitive support
I feel that Halo is not the competitive game it once was, in regards to MLG and the such. Let’s look at Black Ops 2. It features in-game live-streaming, straight to YouTube or Twitch. It has it’s own in-game leagues and competitions. Why can’t a future Halo title do these things? I think that adding more in-game competitive support would be a solid step towards Halo regaining it’s throne on top of the world of competitive gaming.
