if you look at this video this guy basically does it all the time. do I need to download an addon or is it a macro?

btw its not
/roar
/cast Frostbolt(Rank 10)

I've tried that already I've tried it after the frostbolt cast too.

You can also move while using Grenades. Would be nice on Nost.

On retail you could /roar, but i'm unable to make it work on here.

You have to do the emote while running,

/roar (while running)
you stop running when the emote starts
cast the spell

[Joseph]

ok but the guy in the video doesn't do that

EDIT: nvm I see how he does it now thanks for helping me

[Rayzne]

if you watch the video closely you can see that he moves before every emote, sometimes he doesn't move a lot, it's just training to make it look cool

i know what i'm talking about i used to do it a lot
