I like this one, only I found out a couple times the hard way if you hit the button after the last mob dies your pet will target some new group of baddies and go charging off. It's like the Lichborne toggle, use with caution.

I have a question about this. I found that macro on EJ, but it wasn't clarified on there and was hoping you or someone else might know.

Should the auto cast on Claw be taken off when you use this macro? Hopefully that won't sound like a silly question, but it doesn't say one way or another on EJ (that I could find anyway) or in the OP.

Thanks!

I didn't turn the auto cast off. That way it will kind of Claw when you're not Scourge Striking as well.

And yeah, need to be careful. Though if I see my Ghoul tearing off after something else I Death Pact him.

Man, that's pretty cold.

Cold? It's downright frosty!

Instead of using Death Pact, I just bind an easily accessible key to "follow". If my ghoul makes a run, I just hit that.

Also, I use a similar macro to the above, but just use "/cast Claw". This allows me to keep my pet on passive most of the time. This mitigats some of his tendance to run off and possibly pull something.

But you sacrifice some flexibility, like siccing your Ghoul on the tank's target while you burn down and interrupt the caster. Or vice versa, if you have Gnaw on auto-cast and Dark Transformation up.

Still, different playstyles. And as we're talking newbie DK advice, it would probably be better to go with "/cast Claw".

@Brett Porter
This sounds to me like the reason behind this is that, when the ability is on auto-cast, the pet waits for the server to confirm that its ability has finished executing before it starts to cast the next one. Something similar happens to the Warlock's Imp's Firebolt ability and good Destro Locks have all their abilities (or at least the most frequently spammed ones) macroed with something like:
/cast [target=pettarget] Firebolt

Can someone confirm this? Or does this not apply to instant casts since the GCD is calculated locally?
