I usually use these routers on sties and the internet is there with dual natted from the isp side. Wifis are usually eap series tplink and beautifully accessible from cloud of tplink but why has Mikrotik not put together such kind of service till now?

The (one) disadvantage of capsman is that there is no setting for "persistent" changes such that if the customer has no internet or your capsman in the cloud is down that the Caps will still function(of course in local forwarding mode only). It is a feature that I have already requested and hope that one day (soon) it will be provided by RouterOS
