There is definitely some thing odd going on with the AoE Avoidance. As if I could reliably get out of them I would, most are easy to get out of or stun, but the larger AoE's or faster casting ones are a real pain to get out of in time with a little bit of lag. It's kind of bad when you have to almost memorize enemy timings of the AoE's to consistently avoid them. I'm not talking cast times, I am talking knowing that X mob will use Y ability after I use 3-4 abilities of my own or around certain health percents. And unfortunately, it takes a few fights to be able to predict the mobs actions well enough to avoid them that way.
