To those who have tried the PTS, what kind of builds have you enjoyed on Cu Chulainn?

I got tired of waiting for que's after 30 minutes so I have been thinking about different builds. I've found a bit of extra movement speed really works well with his increased auto range and keeping people in range of your 2. He also seems to make a lot of use of Mystical mail, so what builds/items have you guys had success with on the PTS?
