I have never played a Dominator, and it seems to me in reading the musings of my fellow citizens of Paragon and the Isles, that the Dominators are happy with the way Mind Control works for them. So what if we start there, what makes Mind Control so much more groovy for their play or that toon class? Maybe its not that, maybe is solo vs. group, I am merely suggesting we zoom out, look at what is working well so much that those folks will advocate strongly for it to stay the same. Focus on the bright spots so to speak, then from there see if we can find a way to have some of that success propagate to the Controller side of the equation.
Thanks
