arcane rarely firing??

/castsequence reset=0.8 0,0,Concussive Shot
/castsequence reset=0.8 0,Arcane shot
/castsequence reset=0.8 steady shot
/cast arcane shot
/targetenemy [noharm] [dead] 

seems like I get 1 concussive and 1 arcane then it spams steady shot even tho focus is at 70+ ??

Try this -

/castsequence reset=target Serpent Sting,null
/castsequence reset=0.8 Concussive Shot
/castsequence reset=target Arcane shot,Steady Shot
/targetenemy [noharm] [dead]

Take out Serpent Sting if you don’t want it. I am not too sure why Arcane Shot was in there twice so took it out. If you have excess focus just add an Arcane Shot in the above castsequence. Or just mix and match them both till you get it right focus wise.
