I just spent a little while getting the 5 ears for the quest titled 'Lieutenant Astork' and it got me thinking. When the goblins outside Hlint were pansies, this quest was quite easy and the 500 XP rewarded was a nice boost for a character of level 2 or 3. However, I am level 5 and was barely able to take on the goblins even with a summon and the 500 XP rewarded, while still a good boost, does not have the same impact as a quest of equal difficulty.
I suggest that the incremental XP be increased from 100 to 150 or 200 so that the higher level characters who complete this quest get a little bit more for their troubles.
