I'm probably totally wasting my time but I'd like to throw some of my thoughts on what I think is needed for infinite's multiplayer.
- Hardcore and Casual gamemodes: What do I mean by this? I myself enjoy the hardcore/competitive playstyle of halo.One of halo 5's weaknesses was it's always hardcore and sweaty gameplay, there were times when I just wanted to relax and not have to concentrate hard. Social playlists like quick play and coreplay I often couldn't tell the difference in play style to ranked onyx team slayer, even warzone was super sweaty in part to its loose skill pairing. There was no escape and it led to burnout. What's the answer? I believe lowering the skill ceiling is the best way. Have certain gamemodes where the skill ceiling is reduced thereby bringing everyone more in line with each other. This can be done by starting people with autos or removal of certain armour abilities.(I believe this is why fiesta is popular, the skill ceiling is much lower)
- Win EXP system: I never understand people's interest in the CSR system all it shows is time invested but if people like it, leave it in. A much better system I felt was the EXP system from halo 3. Every win in a playlist gave 1 EXP and you ranked up in the playlist up to 5 star general. This shows some level of skill and is something to show off, a level 50 5 star general in MLG was a seriously good player.
- VETO/Random: One thing halo 4 and early MCC showed us is how voting is a terrible way to pick a map. It leads to the same map being chosen over and over and over. Halo infinite should have a veto option where the current map can be rejected and the second generated map is kept. Random is also works.
- Good variety of launch playlists: Halo 5s launch playlists were extremely poor, no social (other than warzone) and 5 ranked playlists which were practically all 4v4 slayer. I believe excluding BTB and reduced playlists were a tactic to force more people through warzone and hence buying packs. In any case for a game to have a good stable playerbase it needs to hit the ground running, when people leave they often don't come back.
- Pregame lobby chat: it blows my mind h5 has no pregame lobby chat! xbl is anti social as it is don't make it worse. Give people an incentive to stay out of party chat. If I'm with a friend why would I go gamechat and then not be able to hear him between games.
- Custom browser: great edition
- no bloom and no health bars
- Weapons range: Something that isn't noticed often is the accuracy falloff with range. h5 does have this to some extent but being able to shoot someone accurately across map is really annoying and limits map roaming. h2 & h3 had a good BR spread with range. If you remember h2 coagulation even with a rifle it was next to impossible to kill someone at range which means on a nice big map you can safely run around and not have to hug cover constantly, same goes for h3. H5 pistol just becomes harder to aim at extreme range but you can still accurately shoot way too far.
- Forced ranked gamechat: I think this worked really well in MW2 search and destroy. It helps the social aspect and meeting new people.
- ranking system: I think the current ranking system works quite well. I'm not a fan of the 6 ranks within a division though. It makes plat 2 > 3 feel totally meaningless you only care about getting to diamond. Halo 2 however had a different colour change every 3 ranks so it was exciting to try to get the next symbol.
- Theatre and forge need to be available on launch: A nice touch would be able to watch a clip with a friend.
- 3 pillars of halo: Melee, shooting, grenades
- melee should bleed through shields, reach *cough*
- Armour abilities: Halo in the last few games has been following current trends rather than creating them. It takes a brave move to go against this specifically because at the end of the day they make games to make money. I believe halo should only have classic movement. Sprint is an illusion of speed, you don't go any faster because they have to make the maps bigger. The endless debate but there's no right answer. I think it's time to be different and go back to halo's roots and not have the same mechanics as every other game. There's just something more fun when everyone is locked at the same speed it's less stressful and feels less chaotic. CS:GO is a good example of a successful no sprint/armour abilities game.
