With no bandsteering Mikrotik is pretty pointless for as a wireless AP these days.
With the Telcos deploying LTE TDD it is only a matter of time until the 2.4 GHz airtime utilisation in urban areas is so high the spectrum could be considered "dead" for public Wi-Fi.
Enterprise access points commonly have a 2.4/5 GHz switchable radio and a 5 GHz radio which helps getting around this issue.
