So I've ran some other stuff now, including WHNM and at this point I think I have a pretty good grasp. Thankfully I had the spellbind and funds to try this all, but I think I have a good grasp on what will work for this class.
For PVE focus I would probably want to go with the Intense, with Crit, Cooldown Reduction and 6% damage rolled on it. That's exactly what I have rolled on my keen weapon right now. The same rolls I would apply for PVP but probably recommend the Keen weapon.
CDR is basically a must have for this class I think. Reaper can use and should use both types of Nostrums. The reason for that is their Position swap and Leash are affected by the Ranged, while all their others are affected by the melee nostrum. Because leash is vital for many chains, it's good to have it up as soon as possible. With the glyph of powerlink it increases your large AOE damage by 20%, and also it chains into Kickback which can then flow into a normal combo.
Before having CDR I would find myself, due to having speed rolled on it before, and having +12 gloves with speed and the weapon +12 that I would run out of skills and basically have nothing off CD. It was fine for PVP moments but in PVE it just didn't work out. With CDR I can basically attack nonstop, and thanks to having a MP regen skill you can use that to keep MP up, though even with that you'll probably have to chug MP pots if you really go at it.
As far as the skill that reduces CD by 70%, Advent of Darkness, there is a pretty simple combo that you can basically do ~3 rotations of before the buff wears off, and this rotation usually ends up with me having aggro. Smite > Kickback > Spiral Blade > Scythe Judgement > Strikedown Blow > Dark Assault > then back into Spiral blade and continue from there. If the boss moves, chain and start over from kickback. Of course by the time the buff is gone I'm also out of MP so its probably for the best it lasts as long as it does.
As far as glyph builds go I think I use a pretty standard one for PVE, It's found here:

For PVP what I use is this:

I'm sure for PVP I'm probably wrong but it works well. Leash onto someone, smite, kickback, spiral blade then use Strikedown blow, cancel that into Dark Assault to KD them then dash in for Burst of Darkness.
Counter is great for PVP as well, so having it up faster I find useful, others mileage may vary. Also for PVP I wear a cruel crux, I believe that's what it's called, the one that increases crit rate upon KD. When you KD them with Dark Assault and then dash in for Burst of Darkness the extra crit damage is more useful than the forceful. Or take out swift crux and use both.
So yeah, I just kinda wanted to ramble on about my thoughts on what to do for the Reaper class. Also to mention that the red weapon skin from WHNM is neat looking. I would ramble on the forums about this but ya know, can't post for another 60 days and all.
