This is also a good pvp build as its annoying as hell with quite a few disables and makes you neigh unkillable. Remember you can heal yourself on mobs if you put 5 combo points on them and then just combo point them to death instead of using a finisher, (gives you 30% hp back every time).
This was one of my rogue builds from lvl 23-50. I have a few more if you're interested. I mained riftstalker for the most part, but you can put points into w/e you feel your playstyle merits.
Also: You will have ~ 5 different teleports using this build and every time you teleport you get increase in dmg absorb/crit chance and I forget what else (movespeed?) for 10 seconds. Its quite a buff, especially since one of the skills tele's you directly behind an enemy AND it doesn't break your stealth so you can instantly assassinate them w/o having to move into position (with a 15% more chance to crit buff on you no less). You can figure out the rest of the combos yourself, but it's a good build imo, I enjoyed it for quite a bit.
