No. The GDC is actually calculated from the SS you're using in Z1. But it isn't as easy as plugging in numbers. You need to take into account Huton which has a specific duration, Kiss of the Wasp/Viper, -10% resists, BFB/IR,oCDs and the sim is set-up so it checks buffs/skills at every interval of the rotation and allows you to freely change the order of abilities, instead of hard coding it. It has a VERY steep learning curve.

As I said, I'll set it up as I'll need to check it through many times and thoroughly test it for accuracy before I want to give out weights for it. I hate giving out half finished or inaccurate numbers. Don't stress yourself with trying to calculate weights at the moment
