Well u cant cast shadowfiend without a target, it then automatically attacks the target, but is then on passive so doesn't attack next mob...

I'm talking instance pulls of 3-4 mobs, and my shadow priest is the only one that needs to drink, so the better i use my shadowfiend the better...

I started using /cast Shadfiend /petaggressive

This seems to work ok, as when mob 1 dies, the shadowfiend comes back to its master then onto the next mob....however there is still the wasted time when it does this, i wonder if having a /petattack command in there too will help. If i add that i will prolly have to spam it once mob 1 dies.

I'm at work now, will try it when i get home tonight.
