If people have anywhere near 80 to 200 Gbps of real world IP traffic and are thinking of using a mikrotik for it, they seriously need to re-examine the revenue from customers that's going through that >50Gbps of traffic, business risk profile and how serious they are about things...

At that scale you'd better have a redundant identical twin pair of routers with 1+1 or N+1 redundant everything (fans, power supplies, routing engines, etc) 24x7x365 service contract, and so on. Not something you can or should do with mikrotik.
