There is a lot of this sentiment, about the lack of (especially low-level) content. Having flipped back and forth from Silver to Gold and back a couple of times, I have to rein in my usual alt-itis (a second or third account helps a little), but I have spent a lot of time running around Westside. Honestly, though it is repetitive, I really haven't gotten irritated or bored by it. It's a little like running around Atlas Park until I was high enough to head over to Kings Row for my radio (now, THERE is a feature this game sorely needs!), only it takes a little longer. Maybe it's because the level transitions were so much lower in CoH, but it does seem much longer before you get to go to a different zone.
In the forums, people say it only takes a couple of hours, but I've only managed it on one character that, unfortunately, is now locked in Gold until I can gather enough Zen to buy his AT.
