Why does the surv macro have in proc, black arrow thats not a proc ?

Trying it tonight when we raid and see how the macro pans out.

Also yes I know of the pvp bow, with the amount of alts I have and boxing, and BG weekend spamming of late, I havent had time to even bother to try for conquest pts, but surely this is the week the bow will drop right ? Hasnt been seen not once since we started and thats been sometime... and there is 2 possibilites of obtaining it, Valiona and Atramedes... So tonight Im lucky punk!!! lol... ok wishful thinking.
