This reset night I went in with flank accuracy, I didn't check my misses but my DPS was 337. Even if I miss some auto attacks or something I think it doesn't really matter if your DPS is high enough. But of course if people are dealing ok-ish DPS due to accuracy issues then it is more important to raise it I guess. Flank accuracy would probably result in an overall accuracy of 98% or so in T9 I think.
