I certainly should have simmed it out beforehand, but this thread tends to move fast so I cut a corner when I shouldn't have.
It was Neiara from frostwolf, I just simmed it out again for him/her and it came out to an even bigger dps loss this time going to sigil from arrow.
Ohhhh k. It was simming out for BM. For survival it is still showing arrow being better but only by 49 dps. Weird.
