Valve events are going for Saudi & UAE money. DOTA2 in China is dying out due to poor quality matchmaking which is why a lot of Chinese pros now play on the SEA server (obviously outside of the rules the Chinese government set).
In general I feel a lot of "e-sport" titles suffer heavily from the GAAS model. The pressure of every developer having to add more and more to the game to keep player retention up and revenue growing. It's also a factor as why CS is a bit of an anomaly for most games as their employees can move to different projects depending on the current focus. E.g. more employees working on CS2, then moving to other areas once released, same with dota2 events.
For me I think a good example of this is possibly Apex Legends, where the foundation of the game is actually really good. It has great feeling guns (for the most part) and heaps of potential for movement tech. It's just massively held back by partly the BR format and the GAAS model. The balancing cycle can really harm the game and at the moment it's pushed forward a lot more to a player retention angle, which results in poor quality matchmaking etc.
In my experience and I NEVER thought I'd say this. But the ALGS tournaments were actually really fucking good. The format they have is actually pretty great and creates a lot of high stakes excitement.
There's a lot of variables that I think heavily effects whether a game actually can become a potential e-sport which would take ages to go through.
