I was taught (in a protestant church) that the Holy Spirit (God in any form) only spoke through / to the prophets in the OT (and people like David, if you don't count him as a prophet). But that the Holy Spirit (God) did not interact in any way with the vast majority of people, and might not interact with them at all for centuries. That He would "come upon" certain ones for a purpose, and then often depart, but was not there, generally speaking.That's what I was taught, for what little that might be worth, or not.
I don't think we are "on our own" today? We have the indwelling Holy Spirit, and whatever way we each experience that, I think we surely have a benefit that the OT people did not? This is one thing that made me more interested in Orthodoxy more quickly, because I was starting to check out the Lutheran church quite a bit, but (among other things) they seem very opposed to any tangible benefit of the Holy Spirit to believers, and I have been repeatedly told that the Orthodox church has no such qualms.
Not that it is "charismatic" and I would not want to see certain disorderliness and things happen within the Orthodox church, but it seems there is an acknowledgement that the Holy Spirit really does things in our lives. I don't like to see that denied.
(I'm not arguing against anyone in particular here or anything, just making a general comment - for what it's worth.)
