Is it possible to macro cover into covering your closest party member?

[TurboSol]

Remove the /wait .5 and leave as is. Tap the button twice and you're golden (although I discourage this macro because pulling with Voke is a silly idea unless you need to pull something 25y away)

As for Cover, try using /ac "Cover" <mo>. Just mouse over the person you're trying to target

or, maybe, they aren't pulling with it, and want a 1 button solution to quickly recover a loose mob.. unless he does intend to pull with it, which I'm with you on that one ;P
