Pulling with mez always introduced an additional method that I always used when pulling with my bard on live.
You can use mez to pull mobs from the back of a room or a corner. The mobs within the initial aggro radius will run towards you, reacting to the mez on their comrade. However, the mobs will run through another group of mobs WITHOUT grabbing aggro from them.
However, once the initial mezzed mob breaks mez and run at you, it'll social aggro everything.
One way of picturing it, the mobs are represented as X's:
X-------X
----X----
X-------X
Mobs are positioned as above and you want a single pull as a bard, and they're not able to be lulled. If you mez a corner mob, only the center/corner mob will come. This will allow you to easily split a camp.
