Well, i'm doing barrows at the moment and i got dharoks axe this morning, and after i got that on my first trip i know anything else i get is pure profit, so i can sit back and relax, not being too bothered if i dont get anything for a while. Although it would be frustrating if i spent a lot of money and lost a profit - not that i think you can with the chaos runes etc. In response to your question without meandering onto my musings i think we do expect too much, when doing (look im doing it again!) a level 3 clue i dont really mind if i get something as clues are generally fun, i've never got a "good" item from a clue and it doesn't bother me.
