Hey with the introduction of TBC there was introduced a nifty feature called focus. Focus is the abilty to "remember" a target without having it target.
One of thinks i use the focus for is when i have to keep sheeping a target while having to dps/target another mob.
So here it is:
/focus [target=focus, noexists] [target=focus, dead] [target=focus, help]
/stopmacro [target=focus, noexists]
/cast [target=focus] Polymorph
This macro will make your target focus and will start to in this case cast polymorph. Also when i push this button again it will be casting poly on the same target as i casted on first time.
This macro can be used for others spells aswell, by replacing the spell Polymorph with the spell you want.
Hope this could be usefull for some :wave:
