welcome to the MOBA cycle.
It starts out well enough, a promising game developed by (usually) an up and coming studio.
It's fun, it's unique, and the developers are well humored and clearly enjoy making the fans happy.
After a while, they refine the game. it starts to get more popular. Then they reach a point where there's some kind of shift in the company. Either they are bought by a larger company, or they become a large company.
Then slowly over time, things begin to change. Suddenly the game isn't as humorous or "fun" anymore. It's still fun to play, but it seems like the soul it had is fleeting. new characters are no longer as unique or interesting, if there were any in jokes, there are no longer any. If there was any story or in-game lore, it's no longer important.
Suddenly you begin to notice that the playerbase itself becomes more hostile and aggressive. This of course as a result of the game's competitive ranking system (if it has one) becoming "winning is mandatory, fun is optional".
The game then embraces the "e-sports" thing.
the community gets worse.
the devs become much more corporate and interested in profit models and keeping things politically correct for one reason or another. You can't take risks on characters, and any gameplay imbalance must be immediately rectified to keep the pro players happy.
and finally, older characters get "updated". usually erasing anything unique and quirky they had.
I played League of Legends for a while.
Riot was never the same after they got bought out by a chinese gaming company. For instance, they stopped making any characters with exposed bones, and there was never another skeleton character ever again. Why? Because the chinese find it disrespectful to show the bones of the dead in media, and instead of keeping regional differences, they just homogenized the regions altogether.
many of the earliest characters were in-jokes related to other games or pop culture, but ever since they went big, nope. can't have that anymore.
And dont get me started on the community.
All Mobas go through the cycle sooner or later, if they live that long that is. Therte's plenty of failed mobas out there that nobody cared about and which just died
