First Corruptor! Arch/Rad IO Build Critique
	Wow, I thought I was the only arch/rad - I've never seen one about before!  Mine's only 44, so I can't give you any final build advice, or anything.  Just a couple things I noticed, though...
For myself, I respecc'd out of stunning arrow.  It's not a bad power, but unless you solo a lot, you won't really need both the stun AND explosive arrow for mitigation, and EA does decent damage (plus KB), where SA doesn't.  I found I never used SA, much as I really do love stuns.
Lingering rad doesn't need too many slots, unless you're after set bonuses.  It comes up fast, and it's claim to fame isn't so much a slow, as a big, honking debuff, esp for AV's.  On the other hand, EM Pulse has a long recharge time.  I'd use some of the slots from LR for some recharge reduction IO's in EMP.  
As much as I like the ranged defense, I would personally take out the t-strikes from blazing arrow, and use 4) devastations plus 2) centriole hami's, or just 2) common ranged IO's, due to the much shorter range on BA.  It's really annoying to have to move forward to be able to use BA - I try to add enough range so it's on par with my other attacks, allowing for a smooth attack chain without having to reposition.  (NOTE:  centrioles are dirt cheap.  I just bought 5 of them for under half a million each, though had to wait a few days for them to all come in.  They do 33% damage, 20% range.  A common range IO does 25% range increase.)  
Good luck and happy shooting!
        
Hey everyone, my first corruptor and I'm looking to make him solid. I've never played archery and played rad on my 50 fire/rad troller years ago. The build is fun but soloing isn't as great as I was hoping. But I'm sticking it out to 50 and going clarion and then see if I'm feeling the same. I went for Perma AM and Hasten and tried to get as much ranged defense as possible. Your advice is greatly appreciated as I tend to waste slots X.x Thanks for the help!
Edit: With Stealth, Hover and Maneuvers I am sitting at 32.6% ranged def.
