Sticky Focus Crowd Control Macro

Description:
The purpose of this macro is to eliminate micro-management of CC. Once a target is identified for control, another target may be selected for healing or damage, and the controlled target will be the victim of renewed control until it is dead.

1. Using this macro if you don't have a focus, or your focus is dead, will set your current target as your focus and then casts your spell.
2. Once you have a focus, pressing this macro will cast your spell on your focus regardless who you have targeted.
3. Right-clicking this macro will ALWAYS change your focus to your current target and then casts your spell.
** Note: Replace Cyclone with a spell name appropriate to your class.
Macro:

#showtooltip Cyclone
/focus [btn:2]
/focus [target=focus,noexists]; [target=focus,dead]
/clearfocus [target=focus,help]
/cast [target=focus,exists,harm]Cyclone;
