@hayhor It's not that easy for a studio. There aren't many anti cheat solutions on the market to begin with. Out of those that have a vast experience, only a part work for this kind of game, as the others may not be compatible, taking up too many resources or not having all the features needed. In the end, there are probably only 2-3 alternative solutions that can meet the expectations in theory, but they all have their weaknesses. Switching to one of these needs some refactoring and a ton of testing to spot and fix some of the issues, which means a lot of time to get ironed out. Games are high risk investments, any can go off the radar in a year's time, a big investment in switching core features at this point can lead the studio to a massive failure. Few will care at that point that they tried.
Best way to fight cheaters at this point is to keep being active against them, by calling them out, recording and reporting them. Because we are millions fo players, we should be far more effective in weeding them out than any anticheat solution. EA, Respawn and EAC need to collaborate more to improve the security of this game as much as possible. The studio needs to also work hard on the reporting system because it lacks heavily on UX side of things.
