The older you get less time you have to give to a game like Valorant when you have family responsibilities and all. Practising 9 hrs a day for an unstable career field isn't possible or worth it for most people once they hit 27-28.
The only ones who actually play well and survive past that age are guys who have a high paying stable org and big reputation for themselves or someone who doesn't really have any other life skill and valorant helps them earn money in short term
