Game Mechanics: More than 4 npc's shouldn't be able to attack a target at once

[Ambrotos]

I reported this before, I'll see if I can find it.

Best way to describe this is odd.

On classic, as a wizard I would play around with root. If you tried to root more than 4 npcs, root would automatically wear off one of the 4 npcs you had rooted, and the 5th one would become rooted. Meaning you could only root 4 max. AOE mez and such, there were no restrictions like this if I recall.

After you rooted the 5th npc, the 4th npcs root would wear off and just walk away. Once you killed one of the 4 rooted npcs, it would come back and attack you.

So this is how I found this out on live pre SoV expansion.

I will try and dig for links also. But I hope what I said helps finding some info out.
