I bought mine from Sam Ash, not Amazon. Bongolation mentions routing problems above, and if he's talking about the bridge, I'd have to agree with him a little, at least on mine. When I took it in to my regular shop for a setup, I was told the bridge would need to be slotted in order to get the saddles back far enough for correct intonation. He said the bridge was mounted in the wrong place. After hearing this, and despite liking the bass for several reasons, I decided to return it to SA.
The errors I've seen with the "good" [sic] W-Rockbass bridges are multiple.
Among the worst are incorrect routing depths relative to those of the asymmetrical neck pocket. This is a huge pain because you simply can't get the action low enough without shimming the neck, even when the fingerboard has practically no relief. This is non-trivial on an asymmetrical pocket that requires a full-pocket fitted shim -- and shimming is always a more complex issue than people realize anyway (I'll have to address this in a tech post some day). Or you can re-rout the bridge.
Likewise, the bridge simply being mounted cockeyed.
Even with the sixty-two different adjustments, you sometimes can't get it to set up properly.
The real killer is the two-point tailpiece shifting or pulling on those gawdawful Streamers they made from construction-grade framing lumber (for which Warwick concocted a fancy name) that's simply too soft and pithy to hold the load in some cases.
I'm unclear on production routines used on these, whether they're routed with jigs or CNT, but the routing is sometimes screwy, as above -- and when I talk about not being able to set up, I'm not even talking about the low action people tend to want on these things, but just acceptable middle-of-the-road clearance. The point is those factory action adjustment tags were meaningless.
I really hope that Warwick finally got their act together with their Chinese production by now (I haven't worked on any new ones for about two years) but the point I'm making here is that this W=good RockBass=bad nonsense is just the typical TB business of people who don't know what they're talking about parroting some glib bit of misinformation or marketing jive they picked up here that sounds good to them. Repeating it to each other gives them the illusion of peer group acceptance or something. Beats me. This makes up a huge percentage of forum traffic everywhere on the Internet.

The Rockbasses had the potential to be excellent values when they were cheaper. There were actually some very nice ones among others that were totally atrocious. Bottom line is that you have to scrutinize each one carefully and actually know what you're doing. W=good RockBass=bad logo dowsing doesn't cut it.
Good luck!
