They're really lucky the Mobile Tac Shooter is a very scarce market
right now only CODM which is in a crippled state especially esports, they arent event like 10% of how dominant MLBB is (which is the cause of Wild Rift's downfall)
R6M moved next year, BFM gone, CS2M isnt real, Standoff is only a thing in Russia, no one plays C-OPS, The netease clone wont go far
Riot is blessed by the fact that the only market holder waiting them is a game that's on semi life support and no one really put effort to try get the cake for the last few years
TLDR: The market isnt at MLBB-dominant level yet, CODM is far from one, no other big IPs try for it either
