Yeah if they have NM title, there is no point getting CM from Fide. I also saw some 2340 with no CM or FM title. Probably they quit chess or their federation dont want to pay money and they dont want or not that serious about titles... Or planing to get IM.
I know quite a few people who have a FIDE rating over 2200 and 2300. Some even being 2350. Is there a reason not to claim the CM or FM title?
