follow prefrence

hey ive been messin around with my new 5 man team, but i cant decide if i should set the 4 slaves to follow the main, or i

Slave A follows Master
Slave B follows Slave A
and so on


im 5 shammy team, i was thinking like master then have A&B&C Following him, which all will be casters, then heal behind that, or am i leaving the healer exposed,

what do you guys run? im gonna try a few ways out, but i cant really find much on prefrence for follow

all follow main. unless you're showing off. In time you'll understand why.
