The game is riddled with cheaters and VAC is a joke. Valve uses its monopoly on the shooter market to make a joke out of their player base.
The investment in Anti-Cheat seems to be next to nothing compared to the money they make.
Sure, there's a giant amount of cheats online and you can't just ban them all. But i think waiting a while until they get banned is not the solution.
Overwatch is riddled with spinbotters, wallhackers and aimlockers!
Someone is looking at the ground 99% of the time and the 1% they look up, it's an instant headshot? WTF do you need Overwatch for? Do your own work, get a KI! Letting the community do YOUR work is pathetic.

They earn millions from the skin market and it's a punch in the face of any loyal player that they made the game free to play.
Cheating has zero consequences now and there's more cheaters than ever before. But I guess the skin market is booming so Valve isn't too unhappy about this.

Trust Factor is a joke, so is Steam Guard! It doesn't do anything apart from 2FA. On my second account, which has no Steam Guard and arguably more griefing and bad behaviour involved, I get less cheaters and toxic teammates than on my main account

A few more things that should not be a problem to add, but are missing in the game:

-more precise matchmaking: I do NOT see any reason why I should constantly get teammates and enemies with 150h and Steam LVL 0 or teammates that have previously been punished for toxic behaviour! Seriously, WTF does your highly praised TruST FaCtOr even do?! Isn't it supposed to prevent match-ups like that?

-matchmaking settings for players that don't have a mic or won't use it. Just let those guys play together, but leave them out of my lobby! It's a massive disadvantage if ony 3/5 players can or will talk.
