Looks good. Tons of recharge. I would prolly franken slot Acid Arrow and Oil Slick, but you'd have to give up the Positron bonuses..
The LotG: Defense in CJ is only giving 0.7% def. (me being cheap, doesn't seem worth it)
I recently got my TA/cold to 50. I plan to make use of all the proc options that come with these sets 
perma jump is ---> /up 1
I was hoping to get some feedback on my "i19" build so I can start getting ahead of the game as far as getting enhancements are concerned. I'm focusing this character (as many different ways as it could go) on damage and debuff as top priority while intentionally not doing a Corruptor. Self sufficiency is something I tend to prize myself on, which is why I have 22-25% positional defense without really focusing on it. Also, I don't really want to purple out any of my builds, which is why I only have Fortunata's Hypnosis (it's just that inexpensive to me).
If anyone sees any major issues let me know. As far as the "i19" portion, that's why rest and sprint are two slotted. One will be for stamina and one will be for health. Performance shifter proc + end mod and miracle and numina uniques.
