the company has been trying to make a really relevant update to the game for some time , because some scenarios are in decline , including this is one of the reasons they are betting so much on the other games they are launching , the only way out would be a re-creation of the game , since that the source code and game engine are already very outdated
I believe in two hypotheses, either RIOT is working in silence to make a defensive system at the level of Epic Games, or the game will really go bankrupt akakakakaka
They will never abandon it, as it generates a lot of revenue for the company to fund other projects (e.g. Valorant). What might happen tho, is that they will create LoL 2 (Hopefully)
It is a very large company to fall with an attack. The truth has been for many years and I think it manages a very large amount of money apart from the brands it sponsors, League of Legends. If it dies at some point, it is not really.
