DRK .. now slightly more engaging than PLD 2.x

[sonatahi]

If Spinning Slash/Power Slash was changed to be more useful than just gaining emnity, DRK would be less of a mainly single combo job without having to re-add a third combo. Otherwise, Spinning Slash and Power Slash is very underutilized, especially with the addition of emnity controlling cross class roles, and almost useless when taking on a role of an off-tank.
