Get into DPS optimisation, like any class trying to stay aligned with raid buffs, snapshotting your dots ect. As OT try doing stuff like cover mitigating tank busts, paying attention to when raid wides happen and mitigating them with reprisal and other skills. In dungeons on things that arn't pally dropping tank stance in trash pulls to pump out dps can be pretty fun. I agree with the post above me though, despite drk having 1 dps combo, having high apm and thinking about best times to dump mana and gauge and build gauge to take advantage of buffs is quite fun.
