The problem with "I have 2000 hours"
It doesn't really mean a lot. At all. The skill difference between a player with 400 hours and 4000 hours isn't going to be all that much, considering how basic the games mechanics are. Sure on certain killers there's a higher skill cap than others but playing blight for 400 hours, and 4000 isn't going to make a huge difference. If you're not good with it after 400, 10x that amount probably won't help. There's an absolute skill ceiling to this game, and it's not being reached after a few thousand hours, but rather a few hundred. And ultimately a large majority of "skill" is more just knowledge than anything. You know more than a newer player does. That's it. As a survivor, after 400 hours you know what amount of distance you can run to safely reach a pallet or vault, and that information does not change after you've played a few thousand more hours. It doesn't become easier to press your w and space keys, there's no real gain in skill at all. As killers, you know what you can and can't do, and how or how not to do it after playing them for a few hundred hours. Again, that information does not change with time played. Practice sure helps but again, there's a skill cap that is absolutely reached and you cant go any higher than that.
Tldr ; hours played = knowledge of the game.
Knowledge = skill more or less.
There's a hard cap on the amount of knowledge to learn. This there is a cap on hours playing meaning anything
