Removal of threat segregation was probably the easier solution atm. You could have optionally implemented districts that combine silver and gold players together, then T's, greens and bronzes together.
It's profitable business for cheat developers, they're the ones laughing and making profit out of idiots, but It can be countered by a hardware-based anti-cheat device.
All software based protections are bypassable, soon even software based protections aren't good enough, hacking is moving from software level to hardware level, Project EPO is one example of this.
There's no guarantee that this game survives another 11 years. People keep saying that's it's dying because it's old, many MMO games older than this are still populated.
This or prevent players from joining lower threat districts altogether. People complain about cheaters while dethreating is one of the biggest reasons why this game is becoming unplayable.
That is not entirely true, adapters for keyboard and mouse do exist. I wouldn't think that game like this is good experience on consoles, too fast paced for game controller, as a matter of fact any FPS or TPS game is worse on consoles imo.
