As Ualaa mentioned, I would recommend using IWT (Interact with target keybind, along with click to move enabled) and have both your IWT keybind and /follow macro on comfortable and easy to reach keys. Additionally, you may want to include another /follow macro on your rogue to follow the healer, so that he can escape melee during whirlwinds while your tank stays in.

*edit* Zugdud do you need to have the pvp set to obtain that output of damage?? Because I have no pvp gear.
No PVP gear required at all, it's just what I happened to have equiped when I last logged out . I have a PVE tanking set that I use for tanking, and while there is definitly room in 5mans to include higher DPS items in lue of tanking pieces(castlebreaker's, bonegrinders, etc)...it's also good to maintain a high level of avoidance to maximize revenge procs.
