This is the crux of the problem in my view. What's with the slowly ramping up nonsense? In a week, about a million people (if not more) will flood the servers and then what?
How does a small portion of the people who'll be around on launch day give an idea of how the systems are faring?
If anything this might give the wrong signal, getting Bioware to think everything's fine only to have servers crashing on launch day.
You might as well let everyone in, and work from there. See if THEN you have any issues, because that's the only scenario they'll be dealing with 7 days from today.
Just my two cents, and mind you, I honestly don't care when I get, I'm just glad I'll probably get to play this weekend.
