Macros for Multiple Mages: Anyone have Ideas on how to use Hotstreak to spam instant cast Pyroblasts effectively?

[caffiend86]

I've been wondering anyone have any ideas on how to work in instant cast Pyroblasts from the Hotstreak talent? I realize it would be fairly easy to do a /stopcasting Pyroblast (below).

#showtooltip
/a [target=focus,help]; [target=focus,noexists];party1
/stopcasting
/cast Pyroblast

However how could you make a macro that wouldn't interupt a chain of casting, ie throwing fireballs repeatedly but when Hotstreak procs a instant cast Pyro is tossed on instead?

nothin you can do to make a spell cast based on a proc/buff you have unfortunately. i wish there was

what i do on mine in pvp is just be moving or hopping when u spam your pyroblast hotkey, wheni hear the sound or see the proc go off i just spam pyroblast/fireblast while moving toward the target then stop to spam scorch/fireball again.
in pve, i just use my main mage's hotstreak proc's, its kinda hard to control the other mages hotstreaks, so i respec'd them and made them icy veins and spam fireballs while the other does scorch/pyro's.
