Rad/ Dark or Rad/ Ice for super tanky

[clowncandy]

I want to make a radiation primary tanker with a secondary that will allow me to tank every instance as I level. I do not care about damage because I never intend to solo. Can someone post a build I would greatly appreciate it. If there is another primary choice that is better for survival let me know also. 

 

Also with the Tanker ATO do you place it in your level 1 attack and just spam it if you do not have a damage aura? Thanks
