This is tricky.
Faze youtube can be as good as you want. There are videos for every audience and it doesn't mean they're good, that's up to you.
But if we talk about esports finance and management then we do have more than enough objective data to conclude they're incompetent
Having so many undeserved free resources, so much "money", so many fans, so many people working for you and yet they've only been able to create a single successful roster in a competitive, international tier 1 esport. Seems really incompetent. A csgo roster that wasn't even able to establish a short era, (that's what someone would've expected right). The reasoning behind the signing is: Let's spend millions on talked-about superstars.
There's no more to it.
"There is a reason that FaZe..."
Bro that reason is called trends, target audience etc. As you yourself said life evolves.
They may be the brand with the most followers, but they have also been around for more years and those followers are due to other things such as call of duty back then or Nickmercs and the mfam stuff today which is completely unrelated to esports.
As I said b4 just look at it as if Ninja creates his own org. You'll say he has 24 million followers but those were already there when fortnite was the no.1 game
