cpt_cam had previously posted this in a thread called evidence of unity strat, but it never really got the attention it deserved. it's been around since fellowship release, and is useful in VERY many places.
Fellowships have no z-axis restrictions. If you can get 3 people on the same x/y axis, you can create one. This means, in missions with the thalassius layout, if you run someone down below you can warp anywhere in the tunnels without clearing, in one of the solt missions you can warp up through the towers, etc. it's also useful in a number of other places, notably some older raid zones.
