Focus on:
100 Mobility
100 Resiliencec
0 Recovery :) you don't need it because you'll have Devour and go invis.
All the remaining points in Discipline. 100 if possible.
YOU CAN TANK ANYTHING. Yes, even Tormentors in Onslaught!

You will only be safe from the front. So be careful that no ads will walk past you and attack you from the side or back.
