In terms of fast IMVU Credits if you are playing horde faction, you should know about the power leveling techniques that are most used for each faction currently. There are few ways to power level your character.

Even a decently geared level 70 can make minced meat out of the Shadow Council Warlocks with their 5k+ HP. Their respawn rate is fast so you will not run out of them. Just be careful of the wandering elite but a max level character can easily take care of those elites.

Besides looting Aldor rep items, you will be getting lots of Nether-weave cloths as well. This cloth is still in demand as well with all the Death Knights power leveling their First Aid skills. And don’t forget the Tailors who require this type of cloth for their crafted items.

So it might not be as good as before but you could still profit from it and will help you with WOW power leveling your character. As it was during the Burning Crusade, the best spot is located at the Legion Hold of the Shadow-moon Valley.

Another good spot is the Arklon Ruins in Nether-storm only if you are a skinner. The Artifact Seekers found in the area can be skinned for Knot-hide Leather.
