I use ISBoxer and run 4x DKs w/ a Disc Priest, I lead w/ the priest and have IWT spammed w/ my dps key, I have my "Back" key bound to my mouse scroll up button so when they reach a target, I just scroll up and they stop running, I have scroll down bound to /follow lead char and its just reflex after a while. I primarily PVP battlegrounds, and have my priest spamming this macro:

/dismount [mounted]
/targetenemy [noharm][dead]
/stopmacro [channeling]
/castsequence [target=targettarget] reset=target/4 Power Word: Shield, renew
/use 14


I use Grid w/ clique for healing individual targets w/ flash heal/pennance.
