The issue were not enmity hold, or how to learn it, itis just that right now, enmity bars are quite different than I were used before.
To make myself more clear with an example, when I keep pull of a group of 6 mobs or more, when at last mobs to down I were used to see other player's enmity just at 50%, but right now there is often that at 90% and sometime happened a pull but when mob alwost died so not an issue.
I wonder if the average player magically become better on its dmg dealing, or there is something else.
