It's looking like a invoker based thorns build sits at the top right now - That brings my question for next season:

I tend to play same class at first, to help gearing a "main" - This season I wanted to go crusader, but since the reward is invoker and that seem to be top dog, I was wondering if I'm correct in thinking that multiple thorns saders would stack horribly? Or is all the thorns damage projected, or are you completely relying on one main char to be hit all the time?
