Normally I don't pay a huge amount of attention to the rewards for bounties, but the one I just received for a "kill dangerous creature" task seems awfully low. The task was for tomb trolls (base level 52 according to the wiki) and the character is level 49 (I found and killed it solo). What's the point of up-hunting for bounties if the reward is going to be on par with what I normally get for critters below my level?

Unless the critter is difficult enough to significantly slow your kill rate, this can actually be quite a large advantage and I suspect it applies on other critter tasks by giving a higher chance for heirlooms/grizzleds to appear as well as on the culls. When I was trying to maximise my AG rewards, I hated the 5 levels below me critter tasks because they took so long it effectively devalued their reward by about 40% due to opportunity costs on not getting another task as soon as possible.
