The Warwick hardware components allow a lot of tweaking...but:
1. the reason behind it is simple: their basses do need a lot of pampering and adjusting quite often; I've owned probably more than 30 basses during these past few years, from the cheapest models to the more expensive stuff - the only ones that need constant attention are my Wicks.
2. the quality of those components is nothing to write home about it: the paint peels off easily, the nut breaks often, and so on.
3. last, but not least: the whole system is not very user friendly, and if you're doing a set up for the first time, it will drive you crazy.
IMO the reason why most folks are either loving or hating the Wicks is that a player has to cope with a lot of particular features (from their neck dimensions, down to the body shapes, weight, hardware, or even the way those balance) in order to play a Warwick bass - some find the transition smooth, others end up hating it.
You are definitely generalizing here. It all depends on the year the bass was produced. I have 2 early thumbs and have never experienced any of the problems you mention here(Of course, I am well aware that these early production run warwicks got more attetion to detail). The Schaller hardware on these has been solid . . . solid brass, that is. But hey, I'm sure a LQ Badass bridge is just better built and more adjustable . . . "sure"
