After doing a lot of testing, Ricochet did serve one good purpose, which was how malicious shadow bans, permanent bans and HWID bans are on PC's. As for the actual prevention of cheaters, it's done fuck all.
They advertised it as this saving grace that would prevent people from cheating and completely clean the game up. All it did was make it a little more annoying to cheat after you've been banned.
In a year, we'll be in the same place as we are now - at the road of little impact. But, as Zebleer said, they'll PR stunt the fuck out of it come preorder time so all of the dick riding hillbillies that think Activision-Blizzard gives a shit about them will give them their 60$.
