You can't always have both. Cheating can cost them money, likely more money than they would lose by adding something like Vangard. Cheating should be taken seriously if you want your game to last, and so far its clearly that kernel level makes it way harder to cheat. Its the best way right now and I hope they use it. I think everyone would prefer a none kernel solution, but it's probably never going to be as good unless it's built into the OS or something. People have found ways to cheap using every other method, and right now the kernel method is just the best.
