I've been playing her a lot on the PTR. I'm probably going to be playing her a lot when it goes live. You'll like the changes - she's just as aggressive as she always was, but this time won't melt. The skill ceiling for her just shot up a couple of stories as there's going to be a lot of strategy as to where you weave your Defensive Matrix into play. Her ult changes are pretty fun too: she doesn't die to her own ult anymore so when you drop it on the point and force people to scatter, you can follow up and force them to fight you or go out of cover to get a face full of explosion.
