Ok, I must say that a SK may be better in PvE than a DW, but the build will affect much in PvP:

A SK PvE is mainly based on 3 attacks: Violent Slice (7 seconds massive stun), Self Descruct Wave (huge damage 15M around) and Cleave (huge damage straight line).
You will even not make use of Bold Strike while farming. In party, a SK PvE maintain agro better than any DW PvE because he can spam Deception (30M around provoke, reduce E.attack 25%) while he can stun the mobs with Violent Slice and reduce greatly his defenses with Draconic Curse.
But without Fear and Curse you can't defend well in PvP.
