Nightblades are just broken in PVP they outclass everything because PVP is about burst damage. This is a Nighblade and Sorc meta in PVP on top of that a Ranged meta also. The best-range toons are Sorcs and Nightblades the best melee at the moment is Nightblade its the best of both worlds. Burst healing was a weakness of both in the past that has been solved, but they did so without a reduction in burst damage output.
