FortiManager

I have one FortiGate and about 6 FortiAPs. I am using FortiCloud and have a license for FortiAnalyzer. 

I have read that FortiManager offers some reporting capabilities that FortiCloud does not. Obviously, I have only a few devices. Is there any reason to think about getting FortiManager? I have noticed that I received point dings on my FortiAnalyzer score because I cannot enable FortiTelemetry without it. Other than that, I am not sure I am really missing anything given the small size of my environment.

Thanks.
