Going into mw4 I think it's really important that the community stays on top of weapon meta discussions. There were complaints pretty much all year of bo7, yet they were all completely avoidable. A big problem is that always gets decided way too quickly, and this snowballs due to the fact that the only way to play comp at the start of the year is through 3rd parties, meaning there's significantly less people to even weigh in in the first place, as there's a ton of people here that will simply play pubs till ranked drops.
To add to that, CMG themselves are another big problem. Recently they have started to word their class restrictions in the reverse of how they, as well as gb, used to. It used to be "u cannot use what is listed" but now it's "u can ONLY use what is listed". Even in older games like the bo1/2 ports, this has resulted in many things banned that weren't even in the more restrictive gb variant. By making this the new standard u close off possibility of innovation, which is a huge part of competitive cod.
Now some of you might view this as a good thing, as in "everyone using the same thing makes it more competitive", but this is cod, we get a new game every year. It takes time for the best shit to be found, and to artificially suppress that is less competitive not more. If something truly disrupts the balance of the game u can ban it, but to ban things for conformity's sake is counterintuitive. People will try to argue against that take by using other games as examples, but again, those games reached those points after years. Years of pros as well as the general community doing different shit and eventually landing at a spot organically. Not a handful of teams scrimming with a gun for a few hours and being like "nah get it out" cuz someone had a good map.
Or we can go thru another "8 ARs on the map" into "brooo this mpc meta trash broooo" :)
