I checked Longsun Zhao's profile on lodestone. To be fair, guys, he does have almost all classes at lvl 60, with the exception of BSM.

However his overmelds neglect CP COMPLETELY. There's NOT A SINGLE CP added to ANY of his white gear/tools. This is in completely opposition to what I usually advice people to do. In my dictionary, CP > Craft > Control (despite the fact that Control materia is the most expensive, Craft second and CP third. So melding should start with control, craft, then max out CP in the end). I dunno how Longsun can craft 2 star items... Maybe he can, but with so few CP, it's going to be very dangerous...
