50NL on Stars - should I skip this level?

[random50]

I've just started playing cash games properly with a long term goal. Since I started with a low bankroll, I started at 25NL. Been doing quite nicely 6 tabling at this level (I'm not a newbie to poker, just a cash game novice) and now I'm rolled to start bringing in 50NL tables.

400 hands in, I see the players are much tighter, which I expected, but they are also *much* more passive, which is pretty much the opposite of what I thought. More often than not, flops are seen without a single raiser. *Nobody* reraises preflop. After the flop nobody seems to want to get involved at all. Is this normal?

If it is, I can't believe this is anything like 100NL and above (is it?!) so I'm wondering if I'm actually going to learn anything useful. Also, because of the way people play, the earnings potential actually doesn't seem any better than at 25NL (in fact, it's probably worse, and higher variance too) Would it do any harm just sticking to 25NL until I'm rolled for 100NL?
