The only thing I would macro is Living Dead but since conditionals aren't in this game (or atleast I don't think it is) I have to set two buttons. One warning the party I used the skill to stop healing me and another to countdown how long the healers have before I need to be topped up.

lvl 55 DRK atm and all I can say is parry might be considered bis secondary stat when you consider the procs that it triggers, Low Blow (timer reset) and Reprisal. Also put all points into STR as you have good defensive cooldowns and most are on 60 seconds timers.

1. Shadowskin = Rampart
2. Dark Dance a very weak version of Keen Flurry but also has featherfoot (20% evasion) effect with DA
3. Darkmind + DA is 30% magic defense for 10 seconds every 60 seconds
4. Shadow wall = Vengeance minus the deflection damage.
