Helpfile says that when hide is mastered it almost never fails, yet I have noticed that warriors (maybe other classes too, but I have mostly been fighting those) easily see where I am at when I hide.

Im playing a class with inherent sneak and anyway it doesn't seem to matter if I move around or stay still. Also Im playing a thief and this has happened in places like Galadon and its sewers, so it cannot be because of a wrong terrain type.

As a newbie to CF I chose a thief especially to have a way to escape warriors, which seems to be the favourite class for lowbie pk'ers here. Do warriors really have some kind of ability which I have overlooked or am I missing something else here?
