Ottilio, you may have just done a quest that didn't gain much Darnassus rep. I posted
a thread recently about my 60 Hunter, who has been doing the quests in Auberdine and Ashenvale, usually getting 150-250 rep each quest. mind you, not all quests give rep, but the vast majority do. Heck, a few days ago, I even did some of the Aldrassil (NE starter area) quests, and got rep for killing level 1-5 mobs. It was almost embarassing- I could kill them by right-clicking on them and running close without stopping. Kill several mobs, go back and loot them all, get the quest items and turn them in- in under 5 min.
I made sure I did it when there weren't low-level characters around, so I didn't inconvenience them.
