Flinch was a good decision by 343 to add to halo. Is see lots of people bashing it but let me explain why it’s a good thing.
-weapons have different fire rates: some weapons shoot slower and hit harder, like the dmr and some shoot faster for lower damage per shot, like the carbine. The dmr causes more flinch per shot over the carbine but the carbine can hit you with more shots overall thus the amount of flinch is equal. With descoping the carbine would suddenly have a massive edge over the dmr due to fire rate causing big issues. There is no way you could ever hope to beat a decent carbiner in a scoped fight.
Different red reticule ranges: a long range gun such as a dmr or a lightrifle could completely shut down a midranged weapon like a BR with descoping in certain situations. If I had a red reticule with my dmr on a guy with a BR who needed to scope in order to get his, he wouldn’t stand a chance. I could pound he out of scope everytime he tried with some clean RR shots forcing him to try and take me with a blue scope and no aim assist at all. With flinch he can at least put up a fight, although admittedly would still be at a disadvantage in such an engagement.
-automatics: the AR would be a more effective gun than the BR outside the BR’s unscoped RRR. It would be easy to knock a BR out of scope and be able to nip it to death. However non hitscan storm rifles and suppressors could not take advantage. Hardly fair. Imagine how bad the saw would be.
Descoping worked in previous halos due to the one gun game aspect of it. Everyone had a dmr, or prior to reach, everyone had a BR. Since all the guns are the same descope worked fine. In halo 4 it would cause many strange imbalances such as the one I listed however.
Flinch isn’t so bad either. It takes plenty of skill actually. A player must react fast an correct his aim no matter which way his reticul may flinch. Not an easy task. Plus isn’t it nice not having to scope 3 or 4 times? It also gives certain controller schemes a distinct advantage. The one where zoom is on the left trigger, (fish stick I think) has the edge over default, as clicking on your left thumbstick a few times quickly can compromise your aim.
If you disagree that’s fine, infact I welcome it. Let’s have a reasonable level headed debate.
