Thiefs can take wank-all when it comes to damage and in dungeons you will die quicker than everybody else if you don't swap between Short Bow and S/P, D/P, DD (depending on style, I love S/P for PvE, not for PvP) when needed to do so, but if played right it's an amazingly entertaining role to play and you can make a big difference when doing so.
Thief is all about speed, it's also the fastest moving profession and you have plenty of things to do in between Initiative-downtime moments, to keep up the pace.
