"i highly doubt masangsoft would be able to match up their salaries and benefits" doesn't take too much to figure out, does it?
Vanguard's codebase is more complex then Microvolts. It cost more to develop and implement than Microvolts ever did make or will make. It's adapted specifically for Valorant. The whole idea is stupid and shows that the person who suggested this doesn't know jack about anti cheats.
Get your boring ass default kernel anticheat like Xigncode and if you implement it properly it'll stop script kiddies. Cost efficiency.
