Im gunna lay down some honesty for ya. Your end gain is terrible even if chrono shift were perma. The best thing I can see from glancing at your build is that you have soft cap for pve on your smash/lethal/ranged defenses which is a nice combination. In fact its something I use for my kin to great effect. With farsight your at what I believe is iTrial soft cap. Again very nice. I have to ask though, did you pick scorpion out of preference, concept or practicality? My opinion on your slotting is this:
Times Crawl - This is way over slotted, to my understanding the power does not stack. For most cases you can add no slots and have it be effective. You really dont need to slot it for slows.
Temporal Mending - I would have gone with Doctored Wounds for the recharge personally and saved a slot
Times Juncture - Im a hard sell here, the only good slotting for this in my personal opinion is Dark Watchers Despair 4 pieces. You get end recover, recharge, more hp to add some to buffer some bigger hits.
Distortion Field - I cant say its bad cause I like that set alot but with Farsight you can get away with 4 slotting Basalisk Gaze and the Lockdown proc.
Time Stop - Prefect slotting for that IMO
Farsight - The slotting here makes me really sad. You completely ignored the defensive aspect of this power! Thats the main reason I chose my defender over a corruptor because that extra buffer + power boost gave me the means to build for other things. Additionally, why did you go three slots of Rectified Reticile. The +6% regen is not going to do that much for you. As a suggestion you could do the LOTG Proc which is super easy to get with hero merits and then 3 Membrane Exposure Hamio-s which are pricey but with some STFs and a little luck you can land them. Alternative frankenslotting would be LOTG +Recharge, LOTG Defense/Recharge, Red Fortune Def/Rec, Adjusted Targeting ToHit/Recarge or just ToHit.
Slowed Responses - Many may disagree but I like the slotitng on this. Other builds may very.
Chrono Shift - I see what you were going for but no really. The main two ways I see this slotted is 6 efficacy adapters or 5 Doctored Wounds and maybe 1 end mod io.
For your attacks I see that you were trying to go with ranged defense but my preference (this is a personal opinion) is to go for your +6.25 recharge bonus with decimations. Additionally the slotting on Psy Tornado kinda makes me sad for the same reason. I would find two slot to go in there.
Also, your hasten is coming at level 4, mistake me if Im wrong cause Im not sure off hand but I thought you still had to wait till level 6?
As for other power pools, I see why you took weave but again, slotting farsight better can eliminate the need and the end drain.
Hasten and Maneuvers I like. Also, with the nice to-hit bonus in farsight I see less need for tactics except for helping to break trough Hi Defense Enemies.
I will post a build later if you like but for now I must be off to the movies. Hope this helps. Again this is all personal opinion on the slotting so take them with a grain of salt.

I appreciate the feedback! I am trying to make adjustments to deal with END issues but a lot of the slotting is there to softcap PvE def and then get Farsight to kick it up even more when needed in Trials.
The goal here is to go with similar defence. I am going to use some of your suggestions and would love to see your build. Thanks again.
Ok so I worked on a build and this might be it!

So has anyone made one of these at all? Anyone able to add some feedback to my last post? 
So, I don't like purples (too much $). I try to get solid defence on a build and enure the powers are effective. I'd appreciate any insight/feedback/comments.
