Currently I have a 50 kin/rad defender I very much enjoy to play and was thinking of rerolling her to a kin/sonic to further push my supportyness. I have a build that I was using on my kin/rad and felt pretty dang strong in most content and ways.

This is the build I have thought up to move to kin/sonic using alot of the same stuff I had on my previous defender would love some feed back as I am deffinatly not much of an expert. 
  
yes I know rune of protection is not perma but up quite a bit and makes u o so tanking to just jump in groups and move around freely.
