The best thing I think Expertise is good for is toons with stuns that have a minimum level toon stunned blue number. In essence, Expertise should raise the minimum level of the guaranteed stun level. What I'm not sure about is if this works with toons like Skeleton King. If anyone can confirm that, I would greatly appreciate it. His Skeledeer kicks out stuns, but there is not a blue skill modifier for its stun. Which brings me to my next question. You have Skeleton King under the disables for runes, but I don't think the "longer disables" stat on runes works for his Skeledeer, as it is a set 2 second stun, every 7 seconds, with no colored number modifiers. Has anyone verified if longer disables works with Skeleton King?
