I'm still leveling, almost 47, but I really cannot see any reason to bring a DRK into Alexander. Reprise doesn't work as an off tank, and the debuff we have is really only so MNK isn't needed for it. The damage is good sure, but I'm pretty sure that WAR can do the same, and keep the 10% damage down debuff way easier than a DRK.

As for MT? >___________> I'd honestly rather OT as a DRK.

I can honestly see tweaks coming in 3.1. I'd be perfectly content if Reprise wasn't limited by parry, but improved by it. I get the ability nearly ever time it's off cool down, but I'm the only one getting hit. When I'm not getting hit, that utility is gone.

Blood Blade is fine as is. In Grit you're actually pretty good on MP as long as your not spamming everything you've got.

I love what Dark Arts does, but I'm still getting used to the MP cost. You def need to make sure your good to use it first.

I'd say defensive CD's we're well off. One for Parry (with DA its evasion too), one for 20% all damage, foresight, one to reduce magic damage, and essentially sentinel as well. Honestly having more control over Reprise would help a lot and would probably make it interchangeable with WAR for pregression OT, and once gear set's in it'd be great for MTing.
