I wouldn't use the ATO's in a tier 1 attack. ATO's, HO's and Purps give awesome percentages and those percentages (in this case) are wasted on a t1 attack (low base damage, doesnt need rech or end reduction).
Also, for a ranged defense build, Thunderstrikes are your bread n butter. It'd be nice if the ATO's were put in a non-Ranged attack like EA or FoA.
It's very easy to cap blasters HP, so I'd make that a priority (decide if your gonna get the HP accolades). I guess you'll want the regen side of Rebirth.
ooh, and I guess you know Swift can take Flight Speed enhancements?
This looks like a fun build. I plan to make one eventually
perma jump is ---> /up 1
Seems like ranged defense builds usually have to make sacrifices.
This build is ugly, but its got the soft cap.
I like Repulsion Bomb and Stupefy so I added it. I normally use RB as a opener.
I chose Radial Paragon so I could steal a slot from Stamina and Drain Psyche.

perma jump is ---> /up 1
Interesting build.That's why I love the forums...you can always find something new! 
I was under the perception that it was better to put the ATO's in a sngle-target power. Is this not the case? The reason I placed it in the T1 attack was so that it would bring the damage of that attack up...which is also nice if I get held or slept.
50 Inv/SS Tank, 50 Inv/EM Tank, 50 FA/SS Tank, 50 Shield/SS Tank, 50 WP/SS Tank, 50 Dark/Dark Tank, 50 EM/Elec Brute, 50 SS/FA Brute, 50 SS/SR Brute, 50 Fire/Kin Controller, 50 Plant/Storm Controller, 50 Earth/Therm Controller, 50 Necro/Dark MM, 50 Bots/FF MM, 50 Elec/SD Scrapper, 50 Arch/MM Blaster, 50 Emp/Psi Defender
Anybody? best place to place the ATO set? if it is better to place in an AoE, I could gain another 4% or so ranged defense. yay! but then I'd lose 6.25% rechg. boo! I'm not so sure that is a good trade.
thoughts??

ATOs, as of now, ARE better used in single-target attacks due to the PPM mechanics (those are about to get reviewed, AFAIK, but I doubt that aspect of it will change.) However, ATOs are better used in later-tier attacks due to two factors:
A ) They give crazy good boost values that scale with your level. Those, being percentages of the power's base, yield better returns as said base goes up. So, from a strict returns POV, you'll get more of a boost to the values of a Tier-3 blast than a Tier-1, simply because the base values are higher. And as said, the T-1 blast rarely needs much enhancement beyond damage and some accuracy, since endurance and recharge are usually pretty low at base. So you'd get great damage but waste great end reduction and recharge reduction on a power that really doesn't need either as much as the rest of the set (especially in Archery. Do you REALLY need snap shot down to a 1-second recharge? That's the time it takes to activate !)
B ) Perhaps more importantly, the ATO procs (at least those that don't work as globals, such as in your case the Blaster one) activate based on the unenhanced recharge of the power they're slotted in. As of now, the Blaster ATO proc is set at 4PPM, so it'll have a 100% chance to activate in a power with a base recharge of 15 seconds (5PPM/12 seconds for the superior catalysed version.) Most T-1 blasts have a 4-seconds or so recharge base, so the proc will drop to about a 25% chance to activate (actually a bit more, but I'm too lazy to calculate the decimals. And for Archery, it drops to about 13%.) So not only will you waste the potential of the enhancements, but a lot of extra damage from the proc. They are exponentially more useful in longer-recharge powers.
NOTE : this is about to change in i24, since Synapse said in essence that 100% activation procs were anathema. But even with the planned changes, PPM procs will still have much higher activation rate in longer-recharge powers. The common approach right now is to slot the Blaster one in T-3 blasts, since those are most likely to give you best bang for your bucks.
In Archery, Blazing Arrow is probably your best bet, even though the uncatalysed version will not activate quite all the time. Explosive is another contender, but it is an AoE and has, frankly, pretty lousy damage compared to BA.
Hope that helps more than it confuses the issue. 
I'm looking for some help and guidance to improve my Blaster. I typically run melee toons and have a good bead on builds for them, but Blasters are a whole 'nuther deal to me. This will be for PVE, and I'm looking for good defense, especially ranged as I tend to hover-blast. I do tend to come into melee range for Drain Psyche and Psychic Shockwave on occasion. I also like +regen and +damage...but I would certainly defer to more knowledgeable advice. I am working on both Clarion and Rebirth depending on the situation. Also, for the ATO set, is this a good place for it, or would I be better served by placing it in another power?
