Is MCMAP useless?

Is MCMAP completely useless? I think it is, besides belting up for 43 jepes points per belt or becoming an MAI for promotion points. I think SOME of the ground fighting techniques are realistically useful but that's it. (also im a reservist MAI so if anyone needs belts dm me my tab expires soon $) What do yall think about mcmap? I literally think it's just a slay fest followed by a knowledge quiz for epme complete people to get their belt points ran. My homie literally only got his green belt so he could get promoted that month when the cutting score dropped super low for him. I think it's just great for promotion tbh
