I assume Sleep will be looked at too once a statistically significant number of BLMs are back in the fight. BLMs have been relying on distance a heck of a lot more than SMNs due to their poor selection of fast casts and its natural that when SMNs are dominating to the extent they were then it was them who got the attention. BLM spams sleep because there's very little else it can do at all in many situations in comparison. If they can work on that and make the two jobs equally desirable in PVP I think a nerf to Sleep/Repose/NW effect durations would be very reasonable.
