Please fix so molten core gives normal rep again. There's an achievement to get exalted with Hydraxian Waterlords, it gives points, so i want it. Achievements which are impossible to achieve anymore are called feats of strength.
Thanks for your query, which was passed along to our development team. This has been taken under consideration, and in a future patch creatures associated with the Hydraxian Waterlords will give full reputation irrespective of your character's level. :-)
