Yea I don't think sneak is supposed to be as effective as it is on this server.
I just tested this on live. Two things.
1. Sneak didn't help, the 2 assisted.
2. King should run straight through at you.

I sneak, con the 2 to make sure their backs to me, both con indifferent. Reaver PH cons ready to attack since he is facing me. Throw a weapon, he charges me and the 2 on sides aggro.
