Parse a few runs on 4.0 then proceed with 3.0. You should be netting an increase in DPS.

My experience with 4.0 vs 3.0 is that upon switching to 3.0, I was able to increase my average DPS by 200 on that fight.
Can't parse on PS4, though there may be a point to mobility, but that's essentially the only reason to use the 3.x rotation.
