for silencing shot, i have a very very nice macro (especially for arena):
/cast [@focus,exists,nodead][] Silencing Shot
set a focus on the other teams healler and i can silence him without even changing current target.....yet if i don't have a focus it will still fire on my current target.....but i was wondering if it was possible to add one more thing to it. Main reason i miss allot of interrupts is because i cannot fire ss as i'm casting my channeled cos or steady shot. So what i'm wondering is is it possible to add something to instant cancel my steady shot or cos to fire my silencing shot?
