To be fair, we're talking one Galaxy, of which both streamers visited a smattering of planets, in a list of galaxies that stretches almost indefinitely, so while their observations deserve some merit, statistically we've seen a super small sample of what is out there.
The gameplay mechanics that are at issue here, can indeed be fixed with a patch. We're mainly talking about moving some sliders from one end of the spectrum to the other, all of which can easily be remedied with a patch.
For a game of this scope, I feel like the true consensus won't come until a few days after launch when a greater player base is able to divine a pattern.
Until then, most of you are grossly speculating some aspects of all of this, that we'll never have the answer to until after release.
