Please see this thread: Is Forms Central part of the Creative Cloud subscription?
Basically, Acrobat XI includes a FormsCentral desktop application for creating PDF forms, but not a subscription to FormsCentral. You get the free level of FormsCentral with Acrobat; for the additional functionality that you're referring to, you need a FormsCentral subscription as well.
Just a slight clarification. Acrobat Pro Subscription that I think you were ask about currently includes a full Formscentral account with unlimited forms and up to 5000 responses per form.
Yes that is what I was asking about Andrew. I just want to make sure that if I subscribe to the Acrobat Pro plan, I will get the unlimited forms and 5000 responses and not be limited like Creative Cloud subscription.
