i use /targetnpc as a marco very easy way to get mobs. just make sure your looking at the mob. :)
You need to be looking at with camera and facing the mob. Seems to be around a 90 degree field of vision.
The exact procedure using /targetnpc in a party for me seems to be: spin the camera, find the target visually, move a little towards the target so I'm now facing the it, hit the targetnpc macro. It's like a crap version of F8 from xi. And there are times when it seems to fail completely or make bizarre selections.
It's nowhere near comparable to /assist when there are alot of mobs around anyway.
The data on who is targetting what must be sent to the client, otherwise you wouldn't get the head turn effect, so I'm sure one day they will bother to add something to copy someone elses target, but for me I prefer just straight tabbing even in a party of 10 because that's based on camera angle, not on camera+player angle.
