1. Overwhelming majority of the (potential) player base is not "knowledgeable" as per your comment
2. It worked for LoL, which has made something like 10x the money of Dota 2. Valorant doesn't have to be "the best" in its category, as judged by connoiseurs, to win its market.
League was the first free derivative of the mod (Dota 2 was released nearly four years after it) and the complexity of the game was massively reduced to the extent that it's marketable in a way that Dota 2 just isn't. Valorant is trying to fight the incumbent while dealing with an inevitable balance trainwreck, and although Riot is going to throw a lot of money at it, it's not clear they realize how spoiled they were with the success of League. I'm sure the game will be around in a few years, but the odds of it largely supplanting CS don't look very good.
