^Yeah.
Even with Seven's intel, it was all Voyager could usually do to escape the Borg by the skin of her teeth. Seeing as the Borg have a superior ability to gather new information on whatever the Federation plans, we're back to the same old pattern on them: most of your measures and countermeasures will only work a couple of times at best.
I hear some of the novel writers are moving ever forward with the whole defanging and familiarizing the Borg thing, but even factoring in what we saw at the end of ST: Voyager, I think they could still fairly be regarded as a next-level kind of threat. Viewing them this way even provides a certain understanding, in the sense that they have bigger fish to fry than the Federation, half a galaxy away.
