Yay, you have soft capped defense to S/L/Energy/Negative while in hide.
And you screwed over other parts of your toon to get it. YAY!
4 slotting CJ is rather pointless.
You want to slot Indom will for defense.
Have fun spending billions of inf on the Kinetic Combat recipes for a build that is only soft capped in hide = not fighting = can have 0 defense and still live.
Are really only going to have that defense at level 50. Say goodbye to most of your defense if you do an SF or PvP in SC.
Fast Healing can do wonders for you.
Strength of Will would prolly do better than soft capped defense.
Since you have no DDR, one hit with a defense debuff will drop your defense, leading to cascading defense failure rendering your hard earned defense useless.
Stalkers have crap for HP (this is why I dislike WP on stalkers personally) This has no real value because of your build, I just had to say it =).
Frankly, I don't know what to build for WP. Could build for +rech. I normally build for +HP then defense on scraps, tanks and brutes. But HP cap can be gotten with accolades and normal IO slotting will get you enough +HP to cap.
Meh, I don't like WP on stalkers =) So I am jaded.
Your character does not have capped defense. Depending on your AT the cap is between 175% - 225%. Your defense is not teal in the combat window, it can go higher. STOP SAYING IT IS CAPPED! The correct term is Soft Cap.
I enjoy playing in Mids. I specialize in Melee Characters, other AT's usually bore me.
lol...yea..I honestly didn't know what to build a WP stalker for, as the defense didn't seem to be as useful as it is on a scrapper, brute or tank.
That's mainly why I just put a build together and asked for suggestions on what to change. 
I'd hate to just say f-it, since he's 44, but then again, I could just leave him with the mixed bag he is now, of SOs and various IOs.
Don't I know you???
I whipped this up to see how close I could come to soft cap while in hide. Please tear my build apart, and make some suggestions that you see.
