You have a decent build going but it could use some tweaks IMO.
Locks have great survivability while leveling. I leveled as Affliction as well and had almost 0 down time. Here is how I would have my build if I were at level 70....
Build Link I removed the points from the healthstone..... yea it's nice but you have haunt + normal healthstone so it's not really needed.
I removed the points from imp. fear.....if you're dotting the mob correctly it should be just about dead by the time it gets back to you, so again, it's not really needed.
And speaking of dotting properly, you were missing UA. So points were moved around to make sure that was available. Some of the points were taken from Bane....They can be replaced as you level. You're typically not going to cast too many shadowbolts (besides the opening one) unless you are facing off against an elite.
I would also pick up the Glyph of Haunt (if it can be used at 70). The damage increase would be great.
Have fun leveling the lock. It will be good to see more of them on Moonrunner. Look up Agrippas if you need any help ;-)
