I'm not sure if this is a bug or intended game play, but I just created an AoE DOT Mage, and I am having an issue kiting large groups of enemies and grouping them up. At most it seems like I can get about 8 enemies to follow me at once but the rest will just stand around completely uninterested. (I have 100% presence)

Once I kill the initial batch then more enemies will run over but it seems like there is some game logic that only allows a very minimal amount of enemies to chase you at once. This is very counter intuitive for a build such as an AoE caster that wants to be as efficient with the mana and group up and kill as many enemies at once as possible.

Anyone else experiencing this. Is it intended?
Thanks in advance.
