I think there's absolutely a middle ground. Players are pretty good at figuring out, after just a few hits, what a monster's apparent average damage is, at least roughly. I think saying it has to be, or should be, either totally unknowable or totally fixed leave a wide excluded middle. I want there to be a degree of uncertainty (as both player and DM), but not total uncertainty. This helps provide that for us.
That said... As for what rolling adds to the equation? For me and my group, it's just more fun. I don't worry about analyzing why. I don't try to figure if it has to do with perceived randomness, or how much information they do or don't have. We just enjoy it more, and I'm quite content to let it lie at that.
