@Auroxis Something i have not seen mentioned here is the new "Fold Space" power, Basically just an aoe Teleport that stacks all of the enemies within like 100 feet right on top of you.
I am personally a big fan of the power, both on teams and solo it amazing for getting the most out of your AOEs, and in this case making sure your Soul drain is well fed.
Do you think it would be worth taking? though the cost is fairly high, needing 3 power picks, it would also get you combat teleport which is fun, and teleport target. I'd probably sacrifice aim and maybe combat jumping? not sure what else.
