Game Mechanics: Ice Giants in Permafrost not moving to engage

[mmiles8]

I ran up and opened the door to the Ice Giant Diplomat, ran back like I was pulling it... Whack whack... nothing, it just stood there, I freaked out thinking it was the lag, but no, gate cast. I interrupted my gate and ran back into melee range to dot it (it's a belly caster), ran back out. It just stood there, no root, no nothing.

I only tested this with the diplomat. Not terribly interested going head to head with that next pull just in case.
