maybe they know they NEED some new maps every now and then but the casual maplist is getting mega bloated, so by making MvM maps they still provide some sort of "real content" (content that isnt just purely just crates and cosmetics) while not making the casual MM even worse

>What's stopping you from doing any of these in a normal game?
Nothing. But in casual tf2 you are by definition playing casually, theres lower stakes, and often times literally no one is speaking, specially since in modern MM you get matched with absolute randoms each time you find a server. And in the case of someone speaking, its usually just having a conversation or banter rather than some tactical call or whatever.
In competitive TF2, even at the lowest level, theres always communication, and EVERY PLAYER is expected to communicate.

Something as simple as calling which side the enemy team is pushing from, or wether they used uber, wether you killed X or Y, wether they're running an unexpected class or hiding somewhere. Some stuff that would work in casual because people dont communicate, wouldnt work at all in competitive because people communicate.

Like if a single guy sees you in a hiding spot in casual it barely matters, but in comp, his whole team will be notified of your hiding spot and come to kill you even if you kill the one guy, so its a major difference and affects the gameplay too.
