There is a trick I use that actually ALLOWS you to pull those types of mobs...but be careful that it isn't a long run to get them to you or you might pull a train.
If your puller has a pet, if you pull with your pet, your pet can/will run around walls, thru doors (even locked ones) to pull mobs.
But BE CARFULL!! You could easily pull trains or alert those "watching" you as to something going on that is not right when you are targeting mobs you cannot get to and/or see.
