343 has really not been focussing on the important changes that need to happen. First the game needs to play right, before all this work on cosmetics should be happening.
The top 3 issues with Infinite are simple, and easy to spot:
1 - Netcode/Desync
2 - Matchmaking algorithm/SBMM
3 - Aim controls on both PC and Controller
The obvious first issue is desync. Until it’s fixed weapons like the Pulse Carbine, Plasma Pistol, and Disruptor are absolutely neutered. And the amount of corner-killing is so ridiculous you even see it happen from the shooter’s perspective sometimes (which has never been the case in Halo, you would only experience it as the defender, and outside of major lag spikes by a much shorter time window). Desync HAS to come first, period. It should be the top priority at 343i.
Second is Matchmaking, right now the system is designed to stack teams so that one is meant to win, and the other is meant to lose, in order to maintain near-50% win loss ratios for every player. What it should be doing is trying as hard as possible to match teams evenly, so that the effort put into the match has more of a factor in the outcome. In a regular play session you’ll more often either win by a large margin, or lose by one, than you will get paired against a relatively evenly matched team. That HAS to change, your w/l% should NOT be factored when matchmaking, only close-skill level matching and connection should.
And finally is aiming. Starting with controller, there’s a whole video going into Infinite’s code, and MCC’s that explains how it’s different, and how it impacts the game. Look up Critical Infinite’s Why Halo aiming SUCKs part 1 on YouTube if you want to check it out. The short version is: In Infinite your reticle does not slow down in a radius around the enemy, but rather only while the enemy is within the reticle already. That makes adjusting your aim during a gunfight far less comfortable and intuitive in Infinite than other shooters on most of the game’s weapons. This needs to be addressed, and the best part is it’s a pretty easy fix, they just need to change some number values in the weapon coding on a per-weapon basis to make it feel better. They can even make it optional so people who actually like the current aiming mechanics can stick with them.
For M&K that’s a trickier topic. M&K suffers a lot and I’m far less experienced with it. But if I had to suggest a fix, it would be to allow the reticle to turn red again, and possibly enable bullet magnetism, but to a smaller degree than controller has. Movement in Infinite is very jarring compared to other M&K shooters, because of your ability to change direction on a dime. A little forgiveness should be afforded to them the same way it is to controller users.
